  • Optical Tracking TechnologyThe ELECOM trackball provides precise cursor movement for superior accuracy so you can get where you want on the screen quickly with less hand movement, improving productivity and efficiency.
  • Functional 8 ButtonsIt is very easy to move in any direction. It comes with 8 physical buttons on the device and the two extra buttons are the scrollwheel tilting that allow horizontal scroll.
  • DPI CursorDesigned with a high-performance gaming optics system sensor and lens. The DPI button can easily change between 500(LOW), 1000(MID) and 1500(HIGH) DPI, making the movements of your cursor faster or slower.
  • Easy Maintenance The ball rolls on three 2.5 mm large artificial ruby ball bearings. They are extremely smooth and the relatively large size prevents dust and dirt from clogging them. So you dont have to clean the ball bearings too often. The ball is held in place by the ball bearings, but can easily be popped out of the device, by pushing it through the hole in the bottom and it can be easily cleaned.

    • Are you still using a mouse????
Style: Wired Trackball Mouse
This review is the for Elecom Huge Trackball (wired version), which I have been using since it came out in 2017--that is over 6 years of daily use, and it is still working as well as the first day it arrived. I use it extensively for photo, video, and sound editing on both a desktop and laptop. My wife's trackball (another brand) broke, so I lent her mine... she refuses to give it back! I am here to buy another one for myself. For those of you who are still using a mouse and are wondering about switching to trackballs, I highly recommend the switch--in fact, I cannot understand why anyone would use a mouse rather than this. The main advantage is that the device does not need to move across a desk or a mouse pad. Because the trackball is stationary, you do not need to make space on your desk to move your mouse. Also, it is easier to be faster and more accurate with the pointer because instead of moving your whole arm, you are using your fingers to position the pointer. The switch from using a mouse to trackball may take a period of adjustment to retrain your muscles and brain--but once you do, I do believe you will find the experience to be very much superior to a mouse. This goes not only for editing software, but for any program or software you will use on the computer. For those of you who have tried other brands of trackballs, and were not that impressed with them, I also suggest that you give this one a try. Before I found this one, I tried every other brand, and I still own most of the best-selling trackballs (which I have been using since my wife has commandeered my own). Even with other brands that do not work as well as this one, I still find the trackball to be superior to the mouse--and there is nothing wrong with the other brands--they just are not as fast, comfortable and ergonomic as this one due to the placement of the scroll wheel and buttons. For those of you trying to decide between a trackball that uses your thumb to move the wheel or uses your finger(s), I would recommend this type with a large ball that uses your finger to move the ball. The reason for this is that you can actually fit up to three fingers on the ball, which allows you to move the pointer across a large screen quickly and very accurately. I know this may sound like a paid advertisement, but it is not... I really do believe that if more people tried this trackball, they would switch as well--the difference is night and day! ... show more

This review is for the ELECOM M-HT1URBK wired version on Windows. I don’t think there is any perfect track ball. Everyone’s hands are different in size and dexterity, to say nothing of right vs left handedness. This trackball is firmly in the right hand, medium sized hand camp. And, this Elecom M-HT1URBK is a mixed bag of very good and not so good. **So first the hardware: It is described as an 8 button track ball, but it really has 10 buttons or switches. The scroll wheel has three, Tilt Up, Tilt Down, and Push In, along with scroll function. Elecom makes several trackballs, and they rightly are divided into “thumb operation” and “forefinger operation.” This is the forefinger type which I prefer. Compared to some other trackballs in the field I find it well built. The anti-skid pads on the bottom are just OK. They work if really clean, the slightest bit of dust and the trackball skids around easily. The soft palm rest is OK now, but time will tell if it gets sticky or degrades with hand oil as most others do. As for the trackball itself, I find it a good size at 52mm. It rides on three ruby red nubs. Those nubs stand a bit higher in the Elecom than other manufacturers. For example my Kensington SlimBlade’s ruby nubs are almost flush with the ball housing. With Elecom’s being higher it takes a bit longer for the ball to gum-up and get sticky with debris. Other reviewers have commented on the not so smooth performance of the trackball itself. I don’t find that an issue. I have a collection of just about every track ball made, going back to the early days of computer GUIs. The early ones were essentially, an upside down mouse. They used steel wheels to track movement and were really rough. Modern trackballs such as this Elecom use reflected light off the ball to track movement. However I find that every modern trackball has to be ‘treated’ out of the box. Here is my method: Get some Engleside Old Fashioned Kitchen Wax & Cleaner. ASIN: B005WW1JF6. Give the ball a good washing with liquid dish detergent. Dry it completely and then use the Engleside to wax it up. Wax it twice, use a soft cotton rag, and be sure to buff to dry between applications. If you do this you will have no complaints about smooth movement. Do it as routine maintenance. Elecom claims on their website they use Omron switches. I have not taken this trackball apart to verify that, but I can say some of the buttons have a very clear and easy click. But, not all the buttons click with the same force. For example the LMB really only clicks well in the forward most finger position. As you move back on the button the force changes to where it won’t click at all. This does tend to slow me down when working, as I have to find the sweet spot to click. The thing is, that is just opposite of the so-called Button #5. The rear of the button is easier to click than the front, go figure. And the other thing about that most used LMB is that it is positioned a bit under the scroll wheel, so I have had to disable the “Scroll In” button as I sometimes hit them both with my fat thumb. Also, I find the scroll wheel to be too far to the rear of the housing. I have to bend my thumb a bit more than I would like. Lastly the “R” or Right button needs to be widened near the top to cover the blank area at about one or two o’clock on the ball. If the “R” button were wider there, it would facilitate Right-Click Drag. In fact I have assigned “Right Click” also to “F2" to help with drag. There is a switch near the base that allows one to switch the pointer resolution between 500/1000/1500. An LED will blink once for the first position, twice for the second position, and three times for the third position. That helps to verify the switch position. **On to the software: Go to the manufacturer’s website and download the latest software. The M-HT1URBK is not currently listed under “Products>Trackball mouse.” Just search for it and it will come up. This review is for the Mouse Assistant for Windows v5.2.00.000 which is current as of this writing. BTW Elecom, it is not a “trackball mouse” it is a trackball pointer, but that is a rant for another time. And, there is a downloadable 23 page PDF manual in English, and some other languages. The install routine is well behaved and requires a reboot. There is no “About” button or check for update button in the software, so it is hard to know if one is running the latest version. The software did recognize the attached trackball and put up the correct picture on the “Allocate button function” tab. There are 46 plus Off assignable functions for each of the ten buttons. And if one fails to assign the two most necessary functions (i.e. for Windows-right and left click) the software puts up a warning box (see pix) and will force one to assign Left Click to a button. As good as that is, inexplicably it ignores the just as important Right Click. However, software labels for the buttons don’t match what are on the trackball. E.g. the trackball button Fn1 is labeled “Button 6:” in the software. If the user clicks on the list box for Button 6, the corresponding button on the trackball picture lights up. But, it does not work in reverse. One should be able to click on the button in the picture and have corresponding assignments come up. Also the scroll wheel tilt is labeled in the software “Tilt left:” and “Tilt right:” but it really should be labeled “Tilt up:” and “Tilt down:” Left and Right is an assignable function, not what one does with a finger. There are other labels that don’t match. If the software can sense the specific model of trackball, it should be able to use the correct labels. As it is, it is just an awkward UI. One can create custom profiles; save and name them. The software defaults to putting an icon in the notification area so it is easy to switch between profiles. There is a feature called “flying scroll” [with apologies to Jay Ward, not Rocky the Flying Squirrel] It is essentially an auto scroll function, and will take some playing with to match your reading speed, but useful, nevertheless. There is a new for this version “Presentation mode” in the current software which the manual hasn’t caught up with yet. I played with it a bit, and it will take some work to see what it does. I’m sure an updated manual would help this. The last tab is for gesture functions. Just be careful of conflicts with Win10 gestures. So all in all there is a learning curve to the feel and the customization for any one individual’s use, but I’m glad I have it and look forward to when it will become more intuitive. ... show more

Style: Wired Trackball Mouse
Update (7/13/2023): I purchased an alternative that seemed close in 'stature' to this mouse because I wanted Bluetooth connectivity, as mentioned earlier for my notebook(s) in case I travel. In general I wanted to just use one mouse. The idea is I use it on my PC (using usb dongle) and then BT elsewhere. Anyway, I got a Nulea, which is nice but it still doesn't hold a flame to this mouse. The back of the Nulea is almost slippery compared to the HUGE and is not as wide, thus, it just doesn't feel as comfortable. My hand sort of just wants to slide off the surface, which makes the material they popped on the HUGE pretty thoughtful. Update (5/10/2023): This has remained my absolute favorite mouse. Wear and tear is so very low even though I use it daily. All I can hope for now is that they make an almost identical updated version, but wireless AND Bluetooth and maybe even a plug-in for a wire so I can buy one to use with my notebook(s), basically a Deft Pro version of this mouse. Again, I personally love and highly recommend this device. This is THE PERFECT finger trackball mouse for bigger hands (and even perhaps, for any hands). Initial Review: I'm one of the unfortunate few index trackball addicts. I cannot use a regular mouse for very long and I certainly can't use a regular mouse for any sort of gaming. That being said, what started me on this terrible journey was a Logitech Marble Trackman - that trusty trackball that's still around. Shortly after succumbing to the trackball, I moved on from that to a Logitech Cordless Trackman Optical, this is where things went wrong. It was for me, the perfect device. A trackball mouse that just seemed to fit perfectly in my right hand. It had a few extra buttons that came in handy for games. My first lasted 2 years and the second lasted roughly the same except just before this one died Logitech decided to discontinue the product - oh, %^#t. I went through phases of tech grief, which are sort of similar to regular grief. I denied that the product was discontinued and convinced myself that the product was cycling, which is when they sometimes discontinue the product and re-release it in a few months with different colors or a different name. This did not happen. I then became quite angry, which I know is quite silly but hey, it happened - because I felt betrayed by the company. How can you, as a company, release 1001 different models of the same mouse but just 1 very, very, very basic model to cater to index finger trackball users? I then entered the bargaining phase, which is where the tech part of this comes in. I took to their forum, Twitter, Facebook, anywhere I figured I could nudge the company into getting the idea that we (index finger mouse users) exist, enough so to at least bring another model to market. I came pretty close to publicly begging. After months and not a peep from the company, I became sad - depressed isn't the word I'd use, again, this is not real grief, just tech grief. I felt sad because I felt really uncomfortable and out of place using a regular mouse and nothing else was working for me. I tried several from various companies like Kensington and the thumb trackball from Logitech (which I cannot use, whatsoever). Finally came acceptance. A slap in the face recently is that the company introduced a new thumb trackball, as if their M570 weren't enough, they released the sleek MX Ergo Plus - Ouch. I bought a new Logitech Trackball, the basic one, you know and that was that for some time. Enter Elecom, a foreign company that doesn't seem to be on the radar yet. One day I decided to do another search for trackball mice and I discovered the Deft or EX-G series, whatever they call it. I bought it and it turned out to be a great cordless Trackball, however, the ball never quite felt right and the shape was just off enough to make it, not quite a gamer mouse for me, though I could use it for everyday PCing, etc. Finally, finally, I get what I want/need. They've released a larger version that is, perfect, for what it's worth. I can't really explain how great it feels so I'll say this. I wrote those previous anecdotes for a reason, so you could/can identify with me. If you've ever used that darn Logitech Cordless Optical Trackman OR the Microsoft Trackball Explorer, which is very similar in feel, then this is it, folks, this is the trackball for you. At first, it feels a bit large, too big in fact - but give it a few, just like the Trackball addiction sneaking up on us, the device eventually becomes just right. I don't quite remember how my hand was when I used the previous devices but I think the most jarring difference is that you won't have to contort your ring finger to right-click, as the buttons lay right under your hand in a naturally open position. The top of the device is large and there's soft padding so you literally just lay your hand down on top of it, it's very comfortable. There are some extra buttons that I haven't figured out how to use since I haven't read the manual (3 function buttons) but you get the staple of an advanced Trackball otherwise, you get a clickable scroll wheel in addition to 2 clickable buttons (forward/backward for browsers) just above it. All of these tend to work universally and are easily bindable in games. The left button is under the scroll wheel in a really great position, IMHO, as my thumb sits right there. The 3rd function button lies beside the right clicker. There's a switch on the device that seems to increase trackball speed manually vs. through software. So far, it's a fantastic device. I got the corded version and am seriously considering buying 2 or 3 more and just putting them away, just in case. I'm giving it some time to see what if anything happens to the device after months of use. Thank you Elecom and Thank you seller and Amazon! Just came back to say that after many months, the mouse still works perfectly. I own 2 now. 1 for my main system and another for my work system. I'm going to buy 2 more as I mentioned before to put away, just in case Elecom decides to call it quits on production. I also have my eye on the Bluetooth model that I will likely use with my mobile devices - I'll see. The HUGE is so great, I'm not sure I want to change the formula. ... show more

    • One of my favorite trackballs, but only with modifications!
Style: Wired Trackball Mouse
I started my journey to find the best trackball mouse I could, for my needs at least. I already own the Kensington stuff, but wanted something a bit more ergonomic, and different. My journey started with the Elecom HUGE trackball, since I had heard quite a bit about it, and Elecom, who I did not know before I started this journey. After reading reviews, I knew I had to work with this trackball, but with some work, it might be excellent. Knowing I would probably want/need new replacement bearings for the stock ruby ones, I went ahead and ordered them with the trackball. I'm pretty handy/mechanical, so I went for it. The HUGE arrived, in a standard cardboard (plain, unmarked) box. I opened the box, and there was a plastic bag inside, with the HUGE in it. Nothing else...nothing. I took it out of the bag, and it looked and felt new. No OEM box, no manual, just the HUGE. Oh well. Let's get going! I am not sure if this is an Elecom thing, or Amazon? Got it out, and set it on the desk. It is indeed HUGE. And, it wobbles. Like a rocking chair. I had read some reviews mentioning this, and mine was no exception. I was pretty bummed about that. Not really an easy fix. I moved on, and went ahead and with an (excellent) YouTube video, replaced the ruby bearings with the replacement balls I got here on Amazon, from another review. The other thing I noticed is that it felt very hollow, and very light. While I had it open, I noticed it had lots of unused space, indeed very hollow. I ended up bringing home a few automotive lead wheel weights, and loaded them up in the extra space...and now it feels like a substantial object, has nice weight to it, and doesn't move on the desk as much...and somehow after the disassembly, re-assembly, the trackball sat more level on the desk, although I still added some layers of electrical tape in just the right spot, to make it sit nicely and level. Now, I had a nice, solid trackball with a very free spinning ball, although not quite a smooth as I had hoped, but certainly acceptable (no comparison with my X-keys L-trac, which I obtained after this, see my review on that). I tried, and failed to get the Elecom trackball software to work well with my iMac 24". I had read about aftermarket software called "Steermouse". I would highly recommend this if you are in a position like I was, it does everything I could want and more (free trial, $20 to keep using past 30 days). After all this, I finally had what I thought was my "end game" trackball! It is very good, and just the way I want it, but I find it not so ergonomic, to me at least. There are a LOT of opinions on this out there, from it being perfect, to horrible. I'm somewhere in between. I do not like the relationship of the trackball and the buttons on the side, I find that my thumb has to be bent in an awkward angle to reach the scroll wheel and buttons on the side, it's OK, but just not comfortable (I have arthritis in my thumb base, so that doesn't help) for me. Your mileage may vary! All in all, I like it. It's got a lot going for it, but it (for me, anyways) needs some refinement. I put it aside for a bit, and am actually using it now again, and going to stick with it for a bit, to see if I can adapt more to it's (to me) awkward hand ergonomics. In the end, I like it, and would do it all over again, it was actually a fun "project" for me. Still yet to find the "perfect" track ball, but this one is awfully close! ... show more

    • The ball drag issue cannot be fixed and is a deal killer for this mouse and I'll tell you why.

Update: 4-18-21 So I finally figured out why no matter what ball bearings you put in this mouse, it will never fix the drag issue from this mouse. It does not matter if you use the "ruby" bearings or "after market" bearings. The issue is not the type of bearings, it's the size of the bearings. And the second reason you will never fix the drag issue on this mouse is because of the type of ball they used. It has a very sticky surface. I'm not sure what type of coating they put on this mouse, but it has a very weird sticky feel. It almost feels like rubber. Between the larger bearings = more surface contact, and the strange coating they put on the ball, it simply ruins this mouse. I finally sent it back and purchased the Kensington Slim Blade Trackball. It has a bigger heavier ball, but it has smaller bearings. The ball is smooth, and rolls like butter with no hesitation from stop to go. Personally, if I could make the perfect mouse, I would use the Kensington ball and bearing set up with the button set up from Elecom and a better palm support. Now that would be a freaking awesome mouse. To be honest, I really miss the Elecom button layout. The Slim Blade doesn't even come close to the switch placement or switch quality. I'm not sure why after all these years, These companies cannot figure out that if they just listened to their customers, they could make a boat load of money if they would just make a good trackball. I would pay double for a mouse with that kind of build and quality. But sadly, I will put up with the button layout on the Slim Blade as the ball movement is perfect, even though the button layout is lacking. Please don't make my mistake and think you can fix this issue. I tried 3 different bearing sets and still could not get it to stop sticking. The palm rest issue could be dealt with as I talk about below. The Silicone spray was a stop gap measure and would only last about a week. Also, Elecom's customer support is ZILCH, NADDA, NEVER. They don't respond to any issues. And for that reason, I will never buy another Elecom Mouse period. So if you want to read my first updated review, be my guest. There are three major issues with this mouse. And I have tried to contact Elecom but it's been two months now and it's been crickets. So what are these three issues? Keep reading. Issue #1 You probably already know about the issue with the ruby red bearings right? I did, and purchased my first new set right out of the box so they would be here when I got the mouse. But the white bearings were super tight. So I purchased the silver grey ones thinking they would be better. But sadly, I would still get "first start" drag issues. I would clean the ball with just plain water and it would get worse for around a day before it would start to loosen up. Very frustrating. I tried warm soap and water and that made it even worse. This was the third separate set of bearings doing this and I was starting to lose hope. But after some serious brain storming I remembered I had a can of WD Silicone Spray. At this point I figured, what can I possibly loose? So I took the ball out and sprayed the end of a Qtip, and thoroughly rubbed each bearing and let it dry. This would fix the issue for about a week and then I would have to do it all over again. As it turns out as stated in my update, the bearings are too big and the ball is too sticky. It is a match made down below. And sadly, there isn't another ball anywhere that you can replace it with. Elecom in their infinite wisdom, used a very odd size for their ball and nobody makes one to replace it with. Issue # 2 So the next issue I started having was a stinging pain in my pinky. Never had this before, and for two days I could not figure out what was going on till I noticed that my hand was not setting on the mouse properly. Why? Because the mouse is not designed to hold your palm at the same level as the ball (see pics), and without even noticing I found that my pinky was trying to support my whole hand. I almost thought this was the end here. I even started looking for other trackballs to replace it with but finding very little. But then I had an idea. Is there something I could use or make, that would give me the support I need. That got me digging around on Amazon till I found the almost perfect solution. And if your looking for and easy fix, this isn't it (it's not hard either). But it did sort of fix Issue # 2 and Issue # 3 at the same time. And it's called Dualplex Neoprene Sponge Foam Rubber Roll Adhesive, 15 X 60 Inches X 1/16" Thick. The issue I had with the Neoprene foam is that it would wear too fast. I would get stress cracks where my hand rested on the mouse. To make it work, I needed some sort of coating on the foam to keep it from wearing out. So what is issue # 3? Glad you asked. Sadly Elecom used a foam pad with some sort of very thin coating on top. And this black coating, after only 4 months was starting to break down. I could see the writing on the wall, and knew that this was going to be a deal breaker for me, as I have read other reviews talking about this and had privately hoped that it was because of a PH balance issue with those buyers. Sadly, that is not true. So I took the Neoprene and built a gradual support pad for my palm and then covered the whole pad with a full Neoprene cover to seal it up. It almost worked flawlessly. This is almost the perfect stuff for this. It's easy to work with and very flexible. The adhesive works perfect for this. It will allow you to stretch a bit and fix while working with it. And then when you have it right, just keep pressure on all the folds for around 1/2 hour and it never moved or pulled and it's been over two days now and it still looks perfect. In fact, it's actually more comfortable now as it keeps my hand from sliding around on the pad like before. But as stated above, needs some sort of coating to make it last. As you can see in the pictures. There was a space of almost 1/2" between the mouse and my palm at a resting angle. This gap was what my pinky was trying to support without me even realizing it. By filling the gap, I not only fixed the pain in my pinky, but fixed the issue with the coating breaking down and ruining this otherwise awesome mouse. Well, sort of. Sadly, I doubt Elecom will ever take the time to read this review, but if it saves one person from making the same costly mistakes I made, it was worth writing this review. ... show more

    • Trackball 5 Stars, Software 2.5
Style: Wired Trackball Mouse
The Elecom Huge is the first finger trackball I have ever used. I have used the famous Logitech M570 and I quite liked it. However I have heard from others that they prefer fingertip balls best. After trying this thing out for a few weeks I can definitely say that I am one of them. The thumb balls were much more natural to use at first since the key placements (at least on the m570) were pretty much identical to what you would find on a regular mouse. It really didn't take me long to adjust to this trackball though. I have heard that break in on this trackball is must and after owning this thing for a few weeks I will have to 100% agree. When I first started to use this trackball It was very notchy. What I mean by this is that when you go to move the trackball it initially sticks until you start moving it. It is really smooth under constant motion though. I almost sent it back after the first day or two, but decided to give it the full week as recommended. I have used it for about 2 weeks collectively since I bought it (off and on usage). Every day that I have used the trackball it has gotten smoother. I would say it is about 90% smoother now and I'm sure over another week it will be perfect. The button placement is actually really great. It seems weird until you actually start using it. The biggest Achilles heal to this thing is the software. Once you actually get everything up and running it's actually pretty good, but it is quite buggy (or at least my version is). Getting to it can be a pain but once downloaded it's pretty straight forward. It is supposed to have gesture functionality but mine has never actually worked. I have read that uninstalling and reinstalling helps but that hasn't helped me at all. I think it's a huge oversight for the software to require that you delete all other mouse software before installing this for it to work. I can't speak for everyone but I have several mice that I use (since I am not comfortable enough to use this thing for gaming yet) and having to uninstall that for this work is crazy. The other thing that this thing does differently from the m570 is the fact that it is much flatter, this can stress your wrists if you don't position your hand just right. I will have to disagree with many people who say that this mouse is only for small handed people. I have pretty big hands and every time I put my hand on the HUGE it feels like it was made for my hand. What helped me is turning the mouse to about the 1 o'clock position (maybe 1:30) and a few inches past shoulder width so my arm slightly rotates outward so my forearm and hand are aligned. The part of my hand that wrests on it makes a backward C shape, from the pad at the top of your hand (metacarpals) around the outside of my hand and stops right almost at the center of the bottom of my palm. I have my hand slightly rotated outward to put the pressure on this backward C part of my hand to not put strain on the delicate parts of my hands. My pointer finger rests in the center of the ball while my middle and ring fingers sit on the buttons. I only bring my middle finger to help with bigger swipes and then I move it back to the button so I don't over stress my joints. For people with smaller fingers or hands you can even use 3 fingers to move the ball, I was actually subconsciously doing this for a few days before I made myself break the habit. This is quite comfortable for me but I think it could benefit greatly from a tilting function. I have seen several 3D printed add on mods to help with this. As it is though at just over 50$ it was definitely worth it to try out. The biggest advice I can give you is to use the natural oils in your hands to break the trackball in, I have heard of some people using some sort of dry lube to help but I don't think you need to go that far. I just played with the trackball a lot while I was at my desk and this really helps to break it in faster. I'm sure someone else who works at a desk full time could break this thing in faster than me, but so far it is getting their. If your bearings don't smooth out after...let's a month, you can always replace the bearings with some other ones, there are a few YouTube videos I have seen that show it in detail (that is if you love everything else about the mouse). For a bit more "traditional" button layout you may want to check out the Elecom Deft Pro that has a smaller track ball and has been reported to have smoother bearings straight out of the box. It isn't as huge but for some it may be more comfortable. I hope this helps! If anything crazy happens for the better or worse I will be sure to right an update. Cheers! ... show more

Quick Summary: MSTE users who don't have an MSTE - get this mouse as it's the closest "replacement" to date. Obviously, if one wants a mouse like the MSTE, then get an MSTE. But even a used MSTE costs a bit and you have to be careful of the cord. If one wants something Less Expensive that closely resembles the MSTE and is also cordless, then this is the best mouse on the scene since the MSTE itself. Update2: Trying to add some slightly better pictures and others that show the MS Trackball Explorer, Logitech Cordless Optical Trackmall, and the smaller Elecom "DEFT" trackball mouse. But some pictures are not loading to the site. Sorry. :( Update1: IMPORTANT NOTE: Waaay down in the comments (the oldest one at the "bottom" should be a link to the Elecom software download page and the English PDF manual. As this mouse is "very new" you *DO* need a more recent Elecom proprietary software to recognize this mouse if you wish to use it's three proprietary function buttons (F1-F3). Long Winded Review =============== This new Elecom Fingerball wireless mouse - the M-HT1DRBK - appears to have been released is June 2017 and has been available on Amazon since July 2017. In August I was about to order a second of the smaller Elecom M-DT2DRBKs when I stumbled over this new **larger** "HUGE" mouse and figured it was worth a try. The M-HT1DRBK just arrived and after giving it a ten minute test spin I just ordered two more. No clue if it will take "1-2 months" for the next batch to arrive, or if the price will drop from $85.99, but would say it is certainly worth the investment. FYI: It actually does say "HUGE" on the mouse itself. :) Comparisons to the MSTE (MS Trackball Explorer) ====================================== 1) It has a nice large "red ball" like a certain MSTE we all know and love. In fact, the Elecom ball is slightly BIGGER than the MS one. There were many reviews about the smaller Elecom mouse's "grey ball" having issues, and several people purchased a "blue" M570 ball to swap with the "grey" one. From my quick tryout of this new mouse with it's "red ball", would say that the quality looks to be significantly better than that of the smaller mouse's "grey" one. An excellent improvement. 2) This mouse is *MUCH LARGER* than the smaller "grey ball" M-DT2DRBK. Excellent for people with "larger" (aka normal sized) hands. 3) It is a bit wider than the MSTE, and Elecom moved one of the three proprietary "Function Buttons" to the right side of the ball. If you use their proprietary software, this would give you "two buttons to the right of the ball" just like the MSTE. 4) MOST IMPORTANT OF ALL. This mouse has a PALM REST. As this seems to be an alien concept to most mouse manufacturers I will state it again - this mouse actually has a place for the palm of one's hand to "rest" while using the mouse, so for the first time since the MSTE, there is actually a trackball that not only fit's one's hand, it is actually COMFORTABLE. Plus it doesn't have teeny tiny thumb-killing buttons like a certain L*git*ch Trackman. Wish I could show a decent side-view of the palm rest, but this can also be seen with via the pics on Elecom's web site. 5) ??? I would assume that being a wireless device, there may be an occasional "lag" in response times, but cannot say for certain. However there does appear to be a wired version of this mouse as well. It's part number (August 2017) is M-HT1URBK. Usage ===== Bulk of this review was written after only ten minutes of mouse use, so haven't had the time to give it an extended run, but observations so far are positive. "Weeks later" - Still great. Haven't tried the Elecom software yet myself (not using the F1-F3 buttons). - Seems to respond MUCH better than the smaller Elecom version (blue or grey ball). - Range seems to be about the same as the smaller one. About nine feet out it gets tricky and Line of Sight is critical. - The "left" button isn't as "tall" as the MSTE's, so my clumsy thumb is hitting the wheel, but this should be a minor issue. - ??? I read elsewhere that the "left" and "right" mouse buttons are "better quality" than the other buttons, that one should be able to tell the difference, that they should have made *all" the buttons "better quality", etc. Haven't noticed any difference between buttons yet. Too busy enjoying having a wireless mouse that actually fits the shape of my hand for a change. Customization - aka The Buttons ======================== So far as remapping buttons, "drivers", and support for various operating systems... Would assume this mouse works as a basic mouse in anything from XP up to Win10. You've got your Left, Right, Forward, Back and Wheel Buttons, plus the three Extra Proprietary Function Buttons F1-F3. Remapping the eight buttons and basic customization is where it gets interesting. Would assume one needs at least version 5.1.0 of Elecom's proprietary software to use/control all eight buttons. For now I am sticking with X-Mouse Button Control which allows configuration of everything except the three extra Function Buttons. Both programs allow for the use of multiple profiles for easy customization across different applications. Elecom's software (and English PDF manual) is available from their website. I will try adding possible links as a "comment" later as this review is too long as it is. Odd Future Issue (?) ================ Since the palm-rest is made of a "soft" material vs plastic, I wonder how it might hold up over time. Will it wear out? Time will tell. ... show more

    • I have mixed feelings about its performance and functionality.
Style: Wireless Trackball Mouse
While it offers some notable features, there are certain aspects that could be improved upon. If you're considering this trackball mouse for your PC or laptop, here's my honest review. Let's start with the positives. The ergonomic design of the ELECOM Wireless Trackball Mouse is commendable. It is shaped to fit comfortably in the hand, providing a natural grip and reducing strain during extended use. The trackball placement allows for precise cursor control without the need for excessive hand movement, which can be beneficial for those with wrist or arm discomfort. The wireless connectivity is convenient, providing freedom of movement and reducing cable clutter on your desk. The mouse connects easily to both Windows and MacOS systems, allowing for compatibility with various devices. The wireless range is generally satisfactory, allowing you to use the mouse from a reasonable distance without experiencing significant lag or disconnection issues. The red trackball is a unique feature that sets this mouse apart from traditional optical or laser mice. The trackball allows you to control the cursor by rolling the ball with your fingers, which can be an alternative input method for those who prefer it or have specific needs. It offers smooth and precise tracking, and the red color adds a touch of style to the overall design. However, there are a few drawbacks to consider. The build quality of the ELECOM Wireless Trackball Mouse is not as sturdy as one would expect. The materials used feel somewhat cheap, and the mouse doesn't have a solid, premium feel to it. The buttons may have some wobble or play, which can be distracting or less satisfying during use. The trackball itself may require frequent cleaning or maintenance to ensure smooth operation. Dust or debris can accumulate on the ball or in the trackball housing, affecting the tracking accuracy and responsiveness. Regular cleaning is necessary to maintain optimal performance, which may be an inconvenience for some users. Another issue is the scroll wheel, which lacks the tactile feedback and smooth scrolling experience found in higher-quality mice. The scrolling action may feel stiff or imprecise, making it less enjoyable for tasks that require extensive scrolling, such as browsing through documents or websites. In terms of battery life, the ELECOM Wireless Trackball Mouse offers decent performance. With regular use, the batteries can last for a reasonable amount of time before needing replacement. However, the battery compartment design could be improved, as it can be somewhat difficult to access and replace the batteries. In conclusion, the ELECOM Wireless Trackball Mouse has some positive features, such as its ergonomic design, wireless connectivity, and precise trackball control. However, it falls short in terms of build quality, scroll wheel performance, and maintenance requirements. If you prioritize comfort and trackball input, this mouse may suit your needs. However, if you value durability and a smoother scrolling experience, you may want to consider alternative options in the market. ... show more

    • Fits Large Hand Like A Glove
Style: Wired Trackball Mouse
The mouse is out of the box and connected for about 30 minutes and works great so far. I have been a 23 year trackball user, and every time I am forced to use a regular mouse like at work, I always look forward to my trackball. I know it's difficult for regular users who have never mastered the art of the trackball to get comfortable, as their is a learning curve, but I love them. Once mastered I never wanted to give it up. I started out with microsoft Trackball Explorer which I loved until it eventually died, then luckily I purchased Logitech Trackman just prior to them discontinuing the model. Logitech doesn't even make a trackball that utilizes the middle fingers other than a cheap 20 dollar model that has no features and is just plain with no gaming abilities! That original Logitech Trackman mouse I had is still going strong after over 10 years, however the software started conflicting with Win10 & 11 and I kept having to disconnect/reconnect to USB to get it to be recognized. I had been looking at the limited availability of a decent trackball mouse over the years and the Elecom product always seemed to be the best design and quality, especially as the reviews were positive. So I pulled the trigger and purchased the Deft model. That small mouse arrived and I knew after like 20 minutes it was too small for my hand. In order for me to have my index and middle fingers properly, comfortably placed on the trackball, my wrist would have to be behind the body of the mouse and floating above the plastic, not in contact with anything. It was a bad combination for me. To slide my hand down and forward to rest comfortably on the mouse, my fingers would be way in front of the ball. So I returned it and ordered the 'Huge' model. At first it was like, Ruh Roh this thing is huge... appropriately named but it looked like maybe oversized?? But after resting my hand on it and then connecting and using the mouse, it was obvious this one was going to be a winner just based on ease of use, comfort, it's just a little getting used to the button placement. I quickly realized the size of the mouse includes the bulk of the mouse closer to the forearm/wrist, which is soft foam and designed to be a wrist rest. It works! My prior mouse didn't have any soft resting area for the wrist but didn't really need it because it fit so perfectly in the hand. Now that I have a wrist 'rest' I am glad that it was thoughtfully included. As for the software to customize, there are plenty of settings to program to my liking, the only glitch was on first launching, it opened in Japanese so it took a minute or two to find the drop down and switch to English. Not enough for a ding on star rating but just a noticeable annoyance. It's a bit early to give this mouse a more definitive review, but I would say out of the box and with a couple of tweaks, it looks like this mouse is going to satisfy my needs adequately. The pointer is smooth and not too slow or fast, and scrolling windows is also not jumpy or to fast. Other reviews were on the mark as this mouse is a winner out of the gate. ... show more

Style: Wireless Trackball Mouse
Hot take. This will be the next PC trend in the wake of RGB lighting and Mechanical keyboards. My wrist thanks me and I feel just as competent gaming with this as I did with my Logitech. Some things I have concluded using Trackballs: - Finger trackballs > Thumb trackballs - You have much more control using your fingers and are provided a larger ball which provides finer control and range of motion. - The experience is akin to combining the best attributes of the trackpad, and the analog stick. - This may sound like a step back but let me explain. An analog stick moves, eases, and stops on a dime. the Trackpad is intuitive, fast and precise, but becomes harder to control when you need to hit a certain pixel point of accuracy. The ball combines the best of both without the drawback - The scroll wheel solution is not entirely perfected... yet - I see several approaches on how to handle the scroll wheel. The first and simplest is keeping the scroll wheel in the usual place if you use a thumb based trackball. This works best but you loose the finger ball advantage I mentioned earlier. So that means you have to come up with something different on the other designs. Kensington Mice have a scroll ring. This is a great idea but has ultimately two underlining problems. First, they patented the daylights out of this. No other brand will be able to use that solution in the name of greed. Second, when gaming the ring can get in the way and cause you to accidentally scroll while gaming if you're not honed in yet. They may pass over time, but I feel it is worth bringing up. In Elecom's case the scroll wheel rests on the thumb AND it tilts for side scrolling too! Ergonomically that makes sense. However if you do a lot of scrolling your thumb will hate you unless you middle click. As a programmer that is not a common luxury for many editors. I work around this by other means, but I would like to share a solution. Simply have a spring load in the scroll wheel so that the scroll wheel behaves like and analog stick. Further back and forth you use the wheel the faster the scroll. This reduces the strain you get from repeated scrolling normally. A simple, but elegant solution. Having listed my overall views on trackballs Let me list my pros and cons to this mouse: Pros: - Fantastic shape, feel and comfort. - Best sensor I have used in any trackball so far. (kensington expert, logitech trackman t-cj12 are the others I have used) - DPI switch is a great tool that I use frequently depending on the application ( I run six monitors so it's great to speed up briefly to move to another monitor and then lower it once I need to get to work in that particular spot. - SO MANY BUTTONS ALL OF WHICH YOU CAN MAP! THANK YOU. cons: - Scroll wheel is better than other similar mice, but still can be improved by making a more fundamental design change (again I strongly suggest substituting with a low profile analog stick instead) - r and fn3 buttons could be better placed. This is the one and only serious blight to this mouse. I have normal sized hands ( read nobody has said to me "hey your hands are Big/Small" ever in my life), and you can clearly see from just the picture itself the buttons are narrow and the mouse itself has lots of unused space they could have used to spread the two out. The followup deft pro mouse Tries to solve this by getting rid of that entirely. I'm guessing because they were trying to make a smaller mouse to accommodate smaller hands, but I personally think the size and shape is just right and only needs to stretch the those two buttons. Having listed all my feedback I am EXTREMELY satisfied with the design, and now am that one weird guy who will tell his friends and family members about how great trackball mice are now. Do yourself a favor and get this mouse. ... show more

I can tell you it’s a substantial piece of equipment and once you set it in place it doesn’t move on the desk. I’m not a gamer, and this device has more buttons than I’ll ever need and they are programmable. I’m just using it for basic mouse functions. The track ball itself is bigger then I was used to but with my pointer and index finger I can move it very precisely and it is very smooth. The buttons click nicely and very easily as well. The Bluetooth connected immediately and all I had to do was slow the cursor speed down a little bit. I’m very pleased with this purchase. Unless I drop it I think it will last forever. ... show more

    • Comfy!
Style: Wired Trackball Mouse
I have long fingers. 7.5" from fingertip to wrist crease. I'm a software developer and also a PC gamer. As I spend more and more time in front of a computer - often 12 hour days nowadays - comfort is critical. In the past I've tried many different trackballs and mice, and everything has had some downside. Recently after starting to have chronic wrist pain, I made it my mission to find the best pointing device. I have tried many different options of mice and trackballs. Up until a few weeks ago, I settled with an older Logitech G5 mouse. Basically, it's the classic MX518 shape. You may have done some research on mice, ergonomics, etc, and read about palm vs claw posture. At my size hands, you're kidding yourself if you think you can pull off true palm posture with ANY mouse. They're simply not big enough. Trust me, I've been searching for the one, but it doesn't exist. With the G5, I found I used something close to palm posture for daily work, then claw posture for agility when gaming. I tried a couple vertical mice. The one I did manage to find that was large enough to wrap my hand around didn't have the wheel in the right place. Additionally, I found the whole movement very clumsy as you have to move your entire forearm. Even if I got better, there was no way I could ever game with it. After a solid week (maybe I'd get used to it?) I determined it was futile. Then I began looking into trackballs. Years ago I tried a Logitech Trackman Marble, and I still had that lying around and decided to give it a whirl. It's alright... wish it was larger to offer more palm support. I am pretty good with it, and can game with it with similar agility to a mouse. The failure is the lack of a wheel. I simply couldn't live without it at work. I've seen coworkers with Kensingtons, and decided to try those next. Kensington Orbit: I immediately wrote off the Orbit for being too small. Kensington Expert: Tried this for a few days. IMHO, the angle on it is all wrong. It's way too tilted... almost as if it was designed for a desk that was too high above your legs, and you're bending your elbow putting your forearm above parallel to compensate. I tried to overcome this with different height wrist wrests, which helped somewhat, but ultimately my wrist was never straight and would cramp after an hour or two. Kensington Slimblade: This is similar to the Expert, but lower and much less angled. On paper, it seemed like it solved the shortcoming of the Expert. I found a wrist rest height that worked well with it. Twisting the ball to function as a scroll wheel? Some people hate it, but I actually kinda liked it. My wrist didn't though... I scroll a lot, and it was simply too much motion involved. I did game with it once, and while I was fairly accurate, it didn't seem very sensitive. Next was this Elecom. Seems Amazon clumps reviews together, so I'll mention I have the URBK aka "Huge" wired only version. This thing is GREAT! Size is nearly perfect. I didn't realize beforehand that the area you rest your hand on is actually some kind of firm foam which is quite nice. The left click (thumb) feels natural, as does the scroll wheel placement. I'm really sold on the thumb scroll wheel. It's the least fatiguing of any setup I've used. My hand falls on it naturally, using the index and middle finger for the ball and my ring finger on the right click. I haven't bothered to install the software to program the other buttons, as I have never really used them on any device. For gaming, this is great! It's definitely faster and more sensitive than the Kensingtons, even when the switch is on my favored medium sensitivity. Sometimes when making a large movement I find myself using my ring finger on the ball as well, but it seems to flow well... much better than hitting the edge of a mouse pad and having to lift a mouse and re position. Bottom line: My fingers are moving, not my wrist, so I am happy and comfortable. I'm considering getting more of these for other computers. If your hands are largish and you struggle to find something that fits well, definitely give this a try! ... show more

    • Pretty nice, but only after some significant modifications.
Style: Wired Trackball Mouse
I love the button placement on this mouse, and they all feel pretty decent except for the middle click at the wheel - it is so hard to press you have to kind of squeeze the mouse with your pinky or else the whole thing will slide. Given that the middle click gets a ton of use when using 3d modeling software, that's the first and most offending thing I noticed about this mouse - my thumb actually got tired using it. The bearings aren't just great, but livable. Also, I think there needs to be a bit more angle to the mouse - my hand sits pretty flat and while I don't think it'll cause any wrist problems, it isn't exactly comfortable. The easiest of these problems to fix is the angle - this is totally a personal preference, so it may be perfect for you and I'm not knocking a star off because of this. There are a number of angled riser models on Thingiverse - I tried a 30 degree riser and thought was a bit too steep, so I settled on a 20 degree riser and now it's quite comfy. Those of us without a 3d printer can make something like this with some stiff foam. Wood would look fantastic if you have the tools and skills. The next easiest, but priciest mod was the bearings - you'll have to open up the mouse for this, but it's well worth it. I swapped the ruby bearings it came with (as mine were at least .08 mm out of round) with some 2.5mm ceramic ball bearings. There's a nice video of how to do this on youtube. For good measure, I applied a drop of teflon lubricant (https://www.amazon.com/gp/product/B003UTX0R8/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1) to the bearing wells. DO NOT GET THE LUBICANT ON THE TRACKING OPTICS - You have been warned. Now my trackball has a pleasant amount of coast and feels pretty good - not like precision machinery, but it's pretty slick Third and most important to me - the mouse wheel button. This one is a little more involved, but really changed how much I like this mouse. The pressure needed to actuate the "middle" click on the mouse wheel is much huiger than the other buttons. The actuation force on all of the other tact switches on this mouse is around 50-60gf, but the actuation force for the wheel microswitch is a whopping 110g. Making it even more difficult to press is the fact that the wheel is halfway between the fulcrum and the tact switch, nearly doubling (!!!!) the force required at the point of contact. I fixed this by desoldering the tact switch and I replaced it with a Panasonic EVQ-Q2B03W (~50g actuation force). The original switch was through hole with only two centered leads, and the Panasonic is a 4 lead SMD package, so I had to rotate the switch a bit so the pads would bridge the original holes, but it works. Also, the Panasonic is about .6mm too short once its soldered in place, so I printed a little shim to glue to the top of the tact switch - was able to really dial this in so there is zero play when you press the wheel. Now the "middle" click is great, I might even say perfect - it was a ton of work to source the replacement switch, and soldering it on was a bit of trial and error, but I'm glad I did this. I cast some lead weights and epoxied them into the hollow cavities on the underside of the wheel - I was hoping to get some coast on the wheel, but I wasn't able to get enough weight for this. It does feel a lot more solid and less plasticky, so it wasn't completely for naught. The software/driver isn't the worst thing out there but it is riddled with annoyances. First off, the wheel rocker switches act kind of like keyboard keys - when you rock and hold the wheel one way, it only sends a momentary signal, then after a short delay, it sends that same signal in rapid repetition. In other words, you can't assign the wheel rocker to a mouse click and be able to click and drag. This is strictly software/driver side - the switch inside is just a normal switch, and you can select the repetition rate in the software. It would be nice if the wheel rocker switches acted like normal mouse buttons. Second - there is a 10-20 second delay after you unlock your computer until your custom button configuration is applied. So any time I step away from my desk and my screen locks. my mouse buttons are all wrong for the unlock screen, and are all wrong until the settings load. Third - the software allows different button layouts to be applied to different programs. This is nice in theory (It's great on my Wacom) but sometimes the layout won't switch, and occasionally I have to force stop and restart MouseAssistant. At this point, I don't use this feature because it causes more problems than it's worth Fourth- a minor niggle, but it still seems like a silly limitation - you can assign arbitrary keys to mouse buttons, but you cannot assign moue clicks in this sequence so modified mouse clicks (such as CTL-LClick to open up a link in a new tab) are out of the question, nor can you assign unicode or extended ASCII characters to mouse buttons, thereby hobbling a potentially powerful feature. If the mouse came with nicer bearings, an easier to press wheel switch and if the software didn't have so many caveats, it would be 5 stars, easily. These issues are serious enough in my mind to knock one star off for each of them, though. I love this mouse now, but I had to put a decent amount of time and about $20 extra in parts/shipping, not to mention void any warranty to get it to the current state. If you enjoy tinkering and don't mind putting some work into this, I'd give it 4 stars, but as purchased, I can only give 2 stars. ... show more

    • I have a good feeling about it, but the hand rest will need some mod/hack
Style: Wired Trackball Mouse
I have recurring problems with RSI from my mouse usage at work. It got worse recently so I decided to invest first in a vertical mouse, but I didn't feel it made that much of a difference. I did some online research and quickly turned my attention to index finger driven trackballs (not thumb), particularly the Kensingtons which looked promissing. After some more review reading I discovered this beast. I was surprised that the package arrived a couple of days early (US to EU shipping). A few notes to the software. I googled "elecom huge driver" and quickly found the ELECOM Mouse Assistant. Even though I downloaded with the english language link and the installer was in english, the context menu was still in japanese :-D By trial and error I opened the settings app and found the dropdown for changing the language (right-click the icon in the tray, choose the 3rd menu item, the dropdown is in the bottom left corner of the window). Other than that the software seems to work fine. Now the unit itself. (disclaimer: I have tried a few other trackballs shortly, but this is the first one I own) I tried all 3 sensitivity settings and all of them are OK. I have yet to decide which one I'll keep using. Trackball size is nice and I think it rolls pretty smoothly (from the reviews I expected worse). I think the accuracy is pretty good as is, but precisely hitting small buttons (closing browser windows, etc.) is kinda hard for me (maybe I will just get used to it). Some reviewers said they (had to) replaced the artificial ruby balls on which the ball rolls. I was convinced that I will do that too, but now that I've tried it I think I'll just use it for a few days and see how it goes. Maybe I'll just end up doing it anyway just to see if it can be even better. Like I said I still need to get used to the trackball experience. Button positioning. I find that so far it's kinda hard for me to roll the ball nicely and left-click without "interrupting my flow" with the ball. I will see how that goes. All the buttons are sort of where your fingers already are, but it takes some getting used to and feeling out the positions so you won't have to look. I'll probably map middle click to some other unused button cause side-clicking the wheel feels a little impractical. Hand rest. I read positive and negative reviews on this and I must say that I don't really like it as it is. Not sure if it is designed for smaller asian hands or something (do they have smaller hands?). When I put my hand on it so that I can comfortably reach the buttons and the scrollwheel, my hand is forced to point a little upwards and that feels uncomfortable. When I however move it forward to lean my wrist a little higher (which feels better), I can no longer comfortably reach the buttons and wheel. I think I'll have to diy some tiny pillow/padding/thing so that my hand can rest on the "hump" in the middle and not my lower palm/wrist which makes my RSI symptoms worse. I will experiment with that. Overall I am excited and I hope I can further improve the experience and find the best way to use this...and get rid of my RSI symptoms... Update: I replaced the artificial ruby balls with ceramic ones (2.5mm) as suggested by other users and I have to say the ball does roll a little smoother. The wired version has one screw hidden approx. in the center under the black sticker so you have to cut through to get to it. Other than that it's rather easy. After a few days my accuracy with the trackball has already improved. I even tried gaming with it and the results are not terrible. ... show more

This is by far, the best computer input device I have used in over 30 years of programming. And I say this despite a few negatives. That is how good this trackball is. The pros: - The trackball is very large, allowing both rapid movement across the screen and very fine, delicate, movements to move the cursor with great precision. - The scroll wheel is not only adjustable for degree of vertical scrolling, but the wheel can be also moved up and down for horizontal scrolling. Pressing the wheel like a button toggles the page and line scrolling. 5 functions in one wheel. - In addition to the 5 function scroll wheel, there are 7 (more than I have ever seen on this class of device) different buttons so with this device you can perform many different functions. There is software that allows you to set each of the 7 buttons to perform any of several functions, or emulate any key, or any combination of up to 3 keys (like Control Shift K). I set it for Left Click, Right Click, Copy, Insert (Paste), Enter, Delete, and I use one button to call a highly used Macro shortcut key combination. In addition the software allows other settings. - The HUGE (yes that is the name) device is just that. It is brilliantly designed so it fits your right hand (left handers are out of luck) with your wrist on a very soft pad and the trackball and all the buttons are manipulable with your fingers only, No wrist or device movement so the seemingly larger footprint is really the same as or less than the area needed by a mouse. Unlike a mouse however, you do not need a flat or smootth surface for the trackball to rest on. It's fine on a pillow, on youir leg, on the arm of a chair, on a table, on top of a book or newspaper, and can operate at almost any angle. -- I have had very bad luck with wireless input devices as I am very sensitive to the latency time between the movement of the mouse and the movement on the screen. This is not a problem with a USB or otehr wired input defice, but with no wire there is always some latency. The Japanese engineers of this Huge trackball have reduced the latency period so much, that I never even notice it on most movements and it is quite small in the 1 out of 70 or 80 moves where Windows or the Apple OS is adjusting and cleaning up its memory. A first class achievement. There is another problem with most wireless input devices: They are energy hogs. If the battery is not rechargable, you might go through batteries very rapidly and expensively. I almost did not buy this for that reason. This requires 2 AA batteries. I have used mine for over 3 months with the original cheap "no-name" batteries that come with the device. Duracell or other class batieries will last even longer and I cannot yet report on this point, but it cannot be too bad as a pair of batteries will last at least substantially longer than a 3 months. It is important that you use the on-off switch to turn the device off if you are finihsed for a session. I generally turn mine on when I boot up in the morning and do not turn it off until I retire at night -- typically about 14 hours. With that, my batteries have lasted over 3 months, so this is pretty impressive. My great enthusiasm exists despite the following negatives: - The instrcutions are not bad. They are terrible! - The website that you have to go to download the software is also terrible and hard to find your way around. - When you do download the software, it is not intuitive as a Microsoft program would be. So you have to work your way through some trial and error and struggle with the on line instructions. Fortunately it is not that complicated. - I am pretty sophisticated with computers and it took me about 4 hours to finally get the device installed and the software configured. Don't worry at first about how you configure the buttons. Use the factory defaults. Then when you get the hang of it and see how time saving it can be, then play with different configurations of the buttons. The Huge trackball is a little pricey, more than twice what a lower-end, wireless, Logitec mouse costs and about 10 percent more than other upscale devices cost. There are plenty that are more expensive and not as good. But I think that if there was ever a good trade off to pay a little more momey for getting quality and functionality, this is it. ... show more
