After three years of hard use I'm writing a review, because no matter how I treat this poor thing it works great all the time. It goes from house to house in my overstuffed laptop bag. I use it with or without the ball, with my feet or hands or elbows. The batteries have needed replacing three or four times total. I originally got it to use with my feet, to save wear on my wrists. I still use it that way sometimes, but it also makes a great mouse or second mouse on the desk. I anticipated that the buttons would break by now but they are still going strong. The only possible negative is that the ball is not as responsive as my other trackball. This is good for feet, less for fingers. I don't know that I'd change it though. Great trackball.

PROS: 1) Well-built/solid construction 2) Ball rolls very smoothly out of the box (no need to replace bearings like on my Elecom Huge) 3) Programmable buttons (Windows only = Reason for 4 stars) 4) On-device memory keeps button macros/configurations with the device 5) On-device DPI adjustment (good for fine-tuning precision with a trackball) 6) Scroll wheel has middle click (can activate autoscrolling with trackball on webpages) CONS: 1) Button configuration SW not available for Mac. (Reason for 4 stars) 2) Scroll wheel is in a bit of an awkward position (but I am getting used to it). SYNOPSIS: All in all, I am very happy with this trackball mouse. I purchased it with the intent of using it with my left hand (even though I am right hand dominant). I use an Elecom Huge for my right hand, but found my hand getting a bit tired as I work on the computer all day (8 hours+). I am using the Adesso T50 to force myself to use my left hand more as I work to prevent potential fatigue and/or RMI. I swapped the left/right mouse button SW using the Windows SW and it DID persist when I moved it over to my Mac (this was a pleasant surprise). I recommend this product if you want to use it left-handed OR if you are looking for a more affordable alternative to the Kensington Expert.

This was an alternative for me because of it costing about half of what my preferred brand trackball costs. Size and shape looked like it would be a good fit. I returned it after several days because it would not maintain tracking or response. The bluetooth dongle was under 2 feet away on my PC. Everything installed and worked properly out of the box, the software app worked fine and did as it said. Then the hardware problems began. Skipping, dragging, stopping completely, multiple battery swaps to see if that caused it. It did not. Additionally, something would not allow the mouse movement to initialize waking up out of screensaver or sleep mode, as any mouse should. A few times it did, most times it did not. Returned and went back to the wired expert pro trackball from the other co. There is a reason I have been using the other brand since they used to be beige for the mac, I just ignored it to be thrifty.

I got curious about this brand of trackballs because they look nice but almost nobody is talking about them online. Well, I think they're great. You get all the functionality of a more expensive trackball but without the price, and with a real (albeit awkwardly located) scroll wheel instead of touchpads and giant rolling logs and other frippery that trackballs use instead of just a normal little scroll wheel. The ball feels nice in your hand and takes longer to pick up grease and crud from your fingers, which means stable rolling for longer. I'm guessing it's using an oleophobic coating like phone screens, but the summary is that I love the way the ball feels, it's soft and almost "gooey" in a way, and slides effortlessly. The part you'll hate is the wireless. I can't stand it. Now, I admit I live in a place where sometimes I can't use Bluetooth headphones sitting RIGHT NEXT TO a laptop because there's so much interference, so maybe you'll have better luck. But the wireless signal strength on this is pathetic, and here's the clincher: It has no intelligence to stabilize the connection, so every time there's a bit of interference, your pointer stops for a fraction of a second. It winds up looking like it's moving at a low framerate, like it's moving at 15hz when your computer is normally 60hz. But! You can fix this by putting the receiver right next to the trackball (I use a USB extension cord) and then the cursor movement is buttery smooth. It basically turns it into a wired trackball with a few millimeters of air gap between it and the receiver. So in summary - good trackball, better at some things than most (especially if you want a scroll wheel that's positioned by your fingers instead of your thumb), and if you get it and it feels like a piece of junk try putting it pretty much on top of the wireless dongle.

Very similar to the Kensington Expert trackball, but better quality, half the price, and the back and forward buttons work with Linux operating system (where Kensington won't). Outstanding, if it lasts -- I quit Kensington (loved the Orbit with scroll ring) because the button switches were junk, and failed in less than a year (sometimes much less) with heavy use.

I bought this because I had surgery on my right index finger and could not use a traditional mouse. This was the best option for switching to my left hand for work. The trackball works incredibly well and you can adjust the speed at which it travels. You do need to pop it out and clean the sensors every once in a while, but that is simple and easy to do. Having four buttons that can be changed with macros was also a HUGE help. I made one left and one rich click, and then I used the other two for keyboard macros that I couldn’t not execute with only one hand. This saved a lot of time and frustration while working from home. Once my right hand fully heals I will replace my standard mouse with this! 1000000% would recommend

There's a lot to like here. Very customizable, high polling rate, smooth action. Problem is, the mouse's X and Y sensitivity values are different, and you can only control Y. You can turn it down to zero with the driver software, but it's still faster than X. How this translates to regular use is that your vertical movements are much faster than your horizontal movements, which makes using the mouse an awkward chore. The scroll wheel is also in an awkward place; you have to move your hand to use your thumb to scroll, but I was somewhat used to this sort of movement using an L-trac. YMMV. You can also only use this wirelessly with AAA batteries. There is no option for a USB cable, which is a very odd choice. This product needs more time in the oven IMO.

I've no real experience with track balls, but my first impression is nearly flawless. Smooth, easy motion from the trackball, big nice clickin' buttons, and a decent price. I've had to knock a star off because the the little lifts that raise the wrist end of the body, (that I suspect I'd prefer to use) are slippery on the glass top table I'm using, and therefore of no use to me currently. Seems something that'd be easily corrected on my end, so perhaps I'll add the star in later. Ah, and I've read a few frustrated reviews and comments regarding how hard it is to take the trackball out. I suspect they have missed the purpose of the hole in the bottom of the device, that allows for the ball to be pushed up and out of its socket. Update: A week later and I remain happy with the device.
