J-Tech Digital Scroll Endurance Wired Mouse Ergonomic Vertical USB Mouse with Adjustable Sensitivity (600/1000/1600 DPI), Removable Palm Rest & Thumb Buttons - Reduces Hand/Wrist Pain (Wired)

UPDATE: April 4, 2019After having this for almost three years, the scroll wheel finally died. I use it a lot, so I'm not sure if that makes this a bad mouse. Is three years good for longevity? The wheel turns but doesn't do its clicky thing or scroll anymore. I thought I could just ignore that, but going all the way over to the scroll bar and clicking the arrows seems too archaic for me. So I'm about to buy this mouse again. That's how much I like it. My wrist hasn't felt any pain since I started using this. And even my kids have gotten used to this vertical mouse when they use my computer.UPDATE: April 1, 2017 (over eight months of use)I was just using my computer, thinking, "Man, I love this mouse so much," and it occurred to me that I should update this to reflect that. Originally I had given this four stars because it was too tall to fit on my keyboard tray as I pushed it in. Right after writing this review, I took the decorative panel off the underside of my desk in order to accommodate this mouse. I have a cheap fake-wood desk, and having that panel off doesn't bother me in the slightest, so it was definitely worth it. That's the main reason why I increased my review to five stars.Also, I've developed a particular grip on this mouse that makes it so I never accidentally push the buttons near the thumb rest. I now grip it looser than I did in the pictures (my palm barely touches it), so I would have to actually stretch out my thumb in order to touch those buttons. I never use them, so this is a good thing. Sometimes my thumb naturally wants to sit closer to the top of this mouse (close to the DPI button). It changes based on how long I plan on holding it.And lastly, I should mention that my wrist feels GREAT. There's no pain for me and hasn't been since I started using this mouse. That's worth five stars right there! Everything about this feels natural and easy to use for me.ORIGINAL REVIEW: July 25, 2016I work at my computer for several hours on most days, and my wrist had been fine until about a month ago. When it would start hurting, I would rest the right side of my hand on my desk and move the mouse around that way. I had no idea that they actually built a mouse that works with your hand in that position. As soon as I saw it, I had to get it.I was looking at a few models, including the Anker one. This one just looked more comfortable to me. I liked how this one had a ribbed surface, and I also liked the separation of the left and right buttons. With the Anker one, I was afraid my middle finger wouldn't easily rest on the right button. I haven't tried holding the Anker one, so I don't know for sure if I was right, but I have a feeling I was, since my fingers rest perfectly on these buttons.I love the feel of this mouse. I grab it right the first time, every time. It's a very intuitive design. The first few times I used it, it felt much like a joystick, but after using it for a week, it's definitely its own thing. It is just SO comfortable. There's certainly no pain in my wrist now. If I was basing this review on feel alone, I would have given it five stars. But, alas, there are some downsides:-- It's too tall! I put my keyboard and mouse on a tray under my desk, and this doesn't fit! This is just so disappointing. If I pull out my tray, it gets stuck on the mouse, and if I wedge the mouse out and then try to close the tray later (it's a habit, so I keep forgetting not to), it falls right off. At least it's wired, so it never actually hits the ground. This mouse is 3.5" at its tallest point. This knocks off a star all by itself. I suppose I should have seen it coming, it being a vertical mouse and all.-- This mouse takes much practice to use it well. It was frustrating to try to use it accurately (I'm a copy editor, so I need to be able to put my cursor in between letters in a document). I was getting a tiny bit better, little by little. It was a slow learning process. But something wonderful happened tonight, which greatly helped the accuracy: I decided to see what this would be like without the hand rest. Now all of a sudden my palm is resting on the desk, which helps me control where the mouse goes. I should have taken that rest off a long time ago. I knew this new mouse would take some learning, though, so I didn't feel I needed to take a star off for that.Here are some details worth mentioning:-- The scroll wheel does click, but not audibly. What I mean is that it isn't a continuously spinning wheel. But it doesn't make a peep. That probably makes some people quite happy, although I don't particularly care either way.-- When I was first getting used to this, I would go to my mouse with my right hand after typing on the keyboard, and I would misjudge the height and bump into it. I stopped doing that pretty quickly, though. I just had to teach myself to raise my hand a little when I went to use the mouse, instead of going straight across.-- There is no easy way to use this left-handed. Sometimes my toddler likes for me to hold her while I mess around on my computer, and that's when I usually hold her with my right hand (because the rest of the room is that way) and use the mouse with my left. That's very difficult to do with this mouse.-- Twice while writing this review, I accidentally pressed the button right under the thumb rest. That is the equivalent of the backspace key in a browser, so Chrome went back a page and freaked me out, since I thought all the stuff I had written here was lost (luckily it wasn't).-- There's no special software that comes with this mouse--you just get the mouse. Sure, that makes it pretty easy to just plug in and use, but sometimes I wish there was a dedicated interface so I could easily change the function of some of the buttons (like that one next to the thumb).-- This slides very easily across my laminate desk. I don't need to use a pad for it.-- I was afraid this wouldn't fit my hand (I'm a woman), but it's absolutely perfect for me. My hand is exactly 7" from the bottom of my palm to the top of my middle finger.A few of those points I just made were negative, but I still don't want to take this review down to three stars. I'm still very happy that my wrist feels better and that this fits my hand. The fact that it doesn't fit on my tray bothers me enough to where I'll probably start using this mouse exclusively with my laptop. But I don't want to go back to a normal mouse for my desktop, so I'm conflicted. But now that I think about it, the underside of my desk has a panel attached to it, making the clearance shorter. I love this mouse so much that I may just take that panel off, which would completely solve my problem. I think this mouse is definitely worth the trouble.

I have a history of elbow/wrist/hand pain in my mousing arm from a career of pointing and clicking on things. At work they prescribed me an Evoluent Vertical mouse which helped considerably. I bought this for home usage when I realised I was leaning to the left at home to try to simulate the same vertical mouse feeling on my home computer. If you haven't tried a vertical mouse you should, even before you start feeling pain. The over-pronated wrist position of normal mice crosses your radius and ulna which compresses all kinds of internal structures and it's not good for you in the long run. Using a vertical mouse takes a few days to get used to but it's worth it. As an added bonus, it used to annoy any of my colleagues who tried hi-jacking my ergo-mouse/keyboard to show me something at my desk... After a few clumsy attempts to click on things they'd always give up and return it to me ASAP.So far I like it a lot. I also tried the Sharkk/Adesso vertical mouse at a shop. I like all four mice but so far I like this one the most. I have the wired version for my desktop.Texture: My Evoluent mouse had a shiny slick texture that never felt that good in the hand and would collect a lot of fingerprint gunkage. This had a matte rubbery feeling surface with grip ridges. The Sharkk/Adesso mouse looked identical but the Adesso had the shiny smooth surface and the Sharkk was matte. I preferred the Sharkk to the Adesso FWIW.Shape: This mouse has a more naturally curved hand shape that feels very natural in my hand. The Evoluent mouse was a simpler lump of rounded plastic. It's a better orientation than a regular mouse but it's not a great shape. I also like the wrist guard on this one - with my evoluent mouse, my palm heel always drags and get sore after a while.Buttons: The buttons on this one feel much more solid and better placed under *my* fingers than any of the other three I've tried. The evoluent buttons always seemed too big and too long for my hands which meant harder actuation. The Sharkk/Adesso ones seemed OK but were more like long leaf style buttons than actual buttons and lacked feel. Some people have complained about the positioning of the thumb buttons on the J-Tech - I haven't had any trouble with them thus far but I remapped them with xmouse (no drivers are included). I guess you could disable them if they annoyed you. The thumb buttons on the Evoluent mouse are quite far apart - so far apart I never used them. The DPI button is large and better placed than the DPI button on the Evoluent mouse (under the palm?). Unlike the Evoluent mouse however, it doesn't have an up/down DPI button and it does it silently - it doesn't have LED indicators to tell what speed it's on. It just does it.Size: The Evoluent mouse might work better for bigger hands - I believe they have wider range of sizes and left-handed models. I'm 5'6" and male FWIW. The J-Tech mouse works well for me but I can imagine someone with bigger hands finding it too small. I'm considering the Sharkk/Adesso mouse for my laptop since it seems a little more compact than either of the other two options.Overall the J-Tech mouse is my favorite vertical mouse of the four I've tried, at least in the hand. I haven't tried the Adesso/Sharkk mice but I'd be willing to try them for mobile work, sacrificing the wrist guard and better shape for more portability. I'm not a fan of the Evoluent mouse at all any more. It's better than a normal mouse but it doesn't seem worth the extra money on ergonomics or longevity (I'm on my second: one burned out in under a year). Lefties and giant ham hands might need to check them out though.
