    • Best Mouse I’ve Used for Long Workdays
Color: Black Gold
I absolutely love this mouse. The ergonomic design is incredibly comfortable and keeps my hand and wrist in a much more natural position, especially when I’m working at my computer for hours at a time. The buttons are easy to reach, it feels smooth and responsive, and the shape is comfortable without being bulky. It also looks sleek on my desk and feels much more premium than I expected. If you spend a lot of time on a computer and want something comfortable, functional, and easy to use, I highly recommend it. Definitely a 5-star purchase! ... show more

    • Excellent Mouse for S to M Hands
Color: Black
I have Med-Large hands which I think is important to remember when you read this review. Hand size is very important when you're considering vertical mice. For me, I switched to vertical mice due to carpal tunnel a couple years ago, and it really helped to eliminate it. I went to Best Buy and tried both the Logitech Lift and MX Vertical. The Lift is for smaller hands and I didn't like the feel of it. So I bought the larger MX Vertical despite the $100 pricetag with the hope that it'd help my carpal tunnel. It did, but unfortunately, now its suffering from the double click issue that apparently is a feature of Logitech mice. So I began the hunt for another vertical mouse that didn't cost +$100. I knew I wanted one that was for Medium to Large hands, so I tried 3 different ones that said they were for larger hands or had similar measurements to the MX Vertical. None of them I ended up keeping for various reasons. So I bought another one hoping for better luck. Pros: This mouse feels great in the hand with a nicely textured surface. It also has some of the most satisfying buttons of any mouse I've tried with a very tactile yet soft, quiet click. The scroll wheel is nice much like the MX Vertical. The shape was exactly as described and felt like a hand shake. Despite the smaller size, I really enjoyed holding this mouse and my wrist did not drag on the mouse pad. Finally it has a rechargeable battery (which can be a con for some) and was under $20. It also comes in different colors. Cons: The con is that my hands are too big. They recommend this mouse for S-M hands vs the M-L of the others I tried, and I definitely agree. My little finger drags horribly if i put my hand in the "correct" placement. I got around this by putting my 1st finger on the left side of the first button and my 2nd finger on the right, and then use my 3rd finger as the right click, which gave my pinky room on the mouse. It worked okay but wasn't ideal. I really wish ProtoArc made a super sized version of this mouse. (Side note: I saw a knock off version of this mouse with the exact same measurements that said it was for M-L hands. Thank you ProtoArc for an accurate description) Ultimately I ended up returning it due to my hand size, but I really wish either my hands were smaller or the mouse was larger so that I could have kept it. Please ProtoArc, make a larger version for those of us with larger hands. If you did that, I'd buy it immediately. ... show more

    • Much smaller than other handshake/vertical mice
Color: Black
This is my third vertical or handshake Mouse , I have had one each of the Lekvey and Anker. Those mouses worked fine until they completely stopped working essentially, this one seem to be a little bit more ergonomical and nicer looking so I took the leap on it. Initially out of the box seems like a really nice Mouse, I like the way it looks and some of the grip pattern on it, but ultimately within a few moments realized that it was not ideal for my hand. In my opinion the mouse is too small for my hand, the previous versions I had are maybe three quarters of an inch taller, on this mouse my hands feel very cramped, almost like if my hand is shoved into too small of a mitten. Additionally this Mouse has a nice taper off the back which is presumably meant to support the bottom of your hand and wrist better but I find that my hand continually slides down the back of the house and onto the desk and further disrupts my hand position. I do not have exceptionally large hands or anything, just normal size hands for normal size man. I tried to take a photo of the mouse in my hand to show the size of it, but my hand completely obscures the view of the mouse , that's how small it is relative to my average size hand. So if your hands are any larger you will definitely have issues if you're used to the taller Mice from other brands. The buttons all felt like they worked great it was just a matter of getting my fingers in the right places to use them and after one day of using it in my hand felt cramped from being in sort of a weird grip position. It felt like my hand was always about to squeeze the mouse out of my grip. It synced up seamlessly and was compatible with my pC and that was very easy but ultimately the hand cramping and potential wrist pain are not starters for me. ... show more

    • The product is basically perfect; I didn't need the packaging to be so pretty... but it was.
Color: Black
I have bought this twice, three times if you count the Jelly Comb mouse I bought before, because ProtoArc bought Jelly Comb). I bought the Jelly Comb mouse for work in 2020, and when I couldn't find Jelly Comb anymore in 2025, I bought the ProtoArc mouse, possibly for my home (?) in 2025. A few weeks ago, the scroll wheel of the Jelly Comb mouse wheel I had at work went wonky. (After six years). So I went to Amazon, found the mouse I'd bought last year that fit my hand perfectly and was basically exactly the same as my 2020 Jelly Comb mouse and helped with my carpal tunnel, and ordered another one. Predictably, it worked perfectly. But I like having a spare mouse around because sometimes they go bad, so I opened up the old Jelly Comb mouse (had to find a video about how to open an ergonomic mouse, but I figured it out), cleaned the wheel with rubbing alcohol, and put some PTFE tape between the wheel and the rubber, and it's working perfectly again. So now I have three perfectly working mice - one for home, one for work, and one for... trips, I guess? Or as a backup? The Jelly Comb mouse was perfectly fine and I would've ordered it again if I could've found it. It's a great mouse that basically lasts forever, and the batteries last so long I forgot the old one even *had* a battery in it, but then ProtoArc went, "You know what? Making our customers buy batteries is silly; we should just include the batteries *and a USB C charging cable*; that'll be a nice extra touch," though they did that, too. Oh, and they also apparently thought, "Sure, we have a USB adapter *and* bluetooth, but what if people want to connect it to, like, two devices but they want to use Bluetooth for both? What if they have, idk, a desktop, a laptop, and a phone, and they want to use bluetooth to connect to their laptop and phone and can plug the USB dongle into their computer? Better throw in the ability to easily pair with TWO devices via bluetooth!" But that's not what inspired me to write this review. It's the packaging. ProtoArc clearly pays their designers very well. The box looks like something Apple would design. When I opened the box I kinda rolled my eyes and thought, "This is a cheap mouse that does not need packaging this pretty." I'm writing this review in 2026. By the time I need another mouse, I can't imagine how they'll have thought how to make this thing better because it was exactly what I wanted in a mouse before. They'll probably have figured out a way to make sure the mouse wheel doesn't get sticky and need taken apart and cleaned after 6 years. (GASP! Maybe they already did... I'll find out in like 6 years 😂 They did a great job. If I lost enough mice that I needed another one, or if enough of them broke that I needed to buy another, I would buy another one from them. I've also thought about buying one of their ergonomic keyboards, that's how much I like their mice. NOTE: ProtoArc did not pay me to say any of this, or offer me anything in exchange for writing this review, and this is not AI. I just really like this mouse. ... show more

    • Almost great, but instead it misses the mark
Color: Black
A small ergonomic mouse, with an DPI button to adjust tracking sensitivity and USB-C charging. Includes a USB dongle as well as ability to pair with two bluetooth devices. The mouse buttons are the very welcome soft click variety that are very quiet and take very little force to depress. Scroll wheel has a little more than average resistance. Fwd and back button are on the left to help with web browsing. Tracking is good and there is lag. BT pairs easily with Windows. I wanted to like this mouse, but a couple of ergonomic issues prevented be from really getting comfortable with it. First, the "beaver tail" like base that extends under the hand is frustratingly boh too small and too large. It is too small such that it catches the bottom of my hand constantly as I use it, whereas if it were larger or smaller that would not be the case. It just happens to hit the sweet spot that it is a problem. The other bigger problem for me is the velvety soft slick coating they used on this making it very slippery in the hand. As a result I find myself having to hold on tighter than I would normally, which is bad ergonomically. I also suspect this coating over time this coating could degrade into that same sticky goo that similar devices with these coatings suffer from. ... show more

    • Surprisingly Comfortable and Versatile — Budget Ergonomics Done Right
Color: Black
Review Image by Trev
Review Image by Trev
This ProtoArc EM11 NL is one of those “low cost, high impact” upgrades—especially if you’re grinding long hours at a desk. It’s not flashy, but it quietly fixes one of the biggest problems in modern work: wrist fatigue. The vertical design is the star here. It puts your hand in a more natural handshake position, which genuinely reduces strain compared to a traditional flat mouse. The built-in wrist rest helps support your palm, making it easier to stay comfortable during long sessions.  Connectivity is another win. You can bounce between multiple devices (Bluetooth + USB) without constantly re-pairing, which is clutch if you’re running a laptop + desktop + tablet setup.  It just makes your workflow smoother. Performance is solid for everyday use. Adjustable DPI (1000/1600/2400) gives you enough control for productivity, browsing, and even light design work.  It’s not a precision gaming mouse—but that’s not what it’s built for. Battery life holds up well, and being rechargeable means no constant battery swaps—small thing, big quality-of-life upgrade. Now, keeping it real: • It’s a budget mouse, so the buttons feel a bit basic • Takes a few days to get used to if you’ve never used vertical mice • Might feel large if you’ve got smaller hands  But once you adjust, it’s hard to go back. Bottom line: If you want a cheap, effective way to improve ergonomics and reduce wrist strain, this is a no-brainer. It’s not luxury—but it’s practical, comfortable, and gets the job done without overcomplicating your setup. ... show more

TLDR: Absolutely go for it!!!!! You'll be missing out on a lot if you don't get this!! Okay fellas, buckle up as I am about to yap about how incredible and awesome this mouse is. I've been a lifelong windows PC enthusiast, and on a budget. Therefore, that meant I used a lot of mice, but budget friendly mice. However, last year I finally jumped ships to a MacBook Air and the trackpad in there blew my mind. It was just fantastic. However, I also edit a lot of stuff, and that meant a lot of clicking and dragging and with the trackpad I had to compromise on the efficiency a lot. So, I decided to get a new mouse. An ergonomic mouse. I wanted to go with a Logitech ergonomic mouse but that was way too expensive and I just know that we're paying more for the name brand and not necessarily the product. So, I continued my search and that brought me to this gem of a product. It was very affordable and cheap. The quality and feel is just fantastic. The material feels so solid and comfortable. The scroll wheel is awesome. You can adjust the DPI, you can connect multiple devices to this mouse. The color looks perfect. Gosh there are keys that you can customize to. (Now, I know you can do that with a lot of other regular mice too, calm down). But hey, the best part of the mouse, your hand posture feels so so so good. There's tiny details that enhance the user experience. There's a tiny extension of a curve where your palm rests which is not really noticeable until you feel it. It took me two days to get used to it. But in just less than a week I'd say I became a pro, and now in two weeks I crave this. For the car enthusiasts this feels so good just like driving as you hold and shift the gear-shifter. Ufff. So good. ... show more
