Evoluent VM3R2-RSB Silver/Black 5 Buttons 1 x Wheel USB Wired Optical 2600 dpi VerticalMouse 3 Rev 2 - OEM

Pros: Comfortable, seems to relieve wrist and arm pain as claimed. Lots of buttons, great tracking feel, accurate. Software seems stable and is highly customizable.

Cons: The lowest button on mouse is useless. I had to disable it because I was constantly clicking on accident. No horizontal tilt scrolling.

Overall Review: If ordinary mice are causing you pain or if you have carpal tunnel, try it. It's worth the $$. I am very happy with it so far.

Pros: Good design, truly ergonomic, big size for those of us with large hands, designed so people with small hands can also be comfortable, vertical design works. I am a gamer, FPS, RTS, MMO, you name it, and using this mouse for gaming works very well.

Cons: The driver software that includes the feature to remap the buttons, etc only works on 32 bit operating system, I found out the hard way as I upgraded from WiinXP Pro to Vista Ultima 64 bit, there is zero support for 64-bit and I'm not happy about it. The grip on it is not great, it almost feels like it's going to slide off your grip sometimes.

Overall Review: After four months I was very happy until upgrading to a 64 bit OS and finding zero support, now I can't change the buttons nor change sensitivity settings, etc.

Pros: I am an intensive PC user and have used the Evoluent vertical mouse for years now. It truly relieves pains in hand and wrist when you're suffering from carpal. Extremely easy to get used to, takes about only half an hour. Very precise. Absolutely worth every penny.

Cons: Little harder to get used to when playing games.

Pros: -Reduces wrist fatigue and pain -Precise -Easily customizable DPI toggle on bottom of mouse (2600, 1800, 1300, 800) -Comfortable -Easy to get used to -Buttons are customizable with free software (X-Mouse, as recommended per Evoluent website)

Cons: -Button customization software did not come with CD (at least this is the case when installing on Windows 7, perhaps it is installed with XP or Vista) -Expensive (but surgery/therapy is even more so)

Overall Review: I recently started a programming course at my university and noticed stiffness and pain appearing in the wrist of my mouse-hand. It got really worrisome when my fingers started tingling. I was in no mood to pick up carpal tunnel at what might be the start of a career in computers, so I came to newegg and found this mouse recommended under their office ergonomics promotion. An absolutely terrific investment; I've noticed a steady decrease in stiffness and the pain has all but gone away. I purchased this early on before I developed advanced symptoms but I feel confident that even those who have carpal tunnel already would greatly benefit from this device (and other reviews seem to testify to this too). I would also highly recommend downloading an anti-RSI software which forces users to take breaks from the computer. The break times are usually customizable and free software is available for both Windows and Mac. Just google "anti-rsi Windows" or "anti-rsi mac".

Pros: no mac support. yes, this is a PRO. nice construction, nice rubberized texture on the grippy parts. works pretty well, even with my big ninja turtle fingers. it made my wrist pain a little worse for a few days, then it completely went away. gaming was a little weird at first, but i got used to it.

Cons: it's a pretty tall mouse, so it might not fit in an under-desk keyboard shelf thing. rattles a little when you set it down. you might knock it over a lot if you struggle with basic motor skills.

Overall Review: great idea, great execution. bought a previous model like five years ago for like $65. now it's still in that price range at many retailers. five years later. thought the price would have come down, but i guess not. might have something to do with the variable resolution on the new model -- which is really cool.

Pros: Wonderful feel and far better posture than conventional mice

Cons: I use this on a Mac and there are no supplied drivers/conf options. Although it will work out of the box, I want to be able to disable the lowest (3rd) button, as I seem to naturally want to press it, as well as customize some of the other buttons/wheels. The Evoluent website *STATES* that the low volume of Mac usage does not warrant a custom Mac driver, and gives links to 3rd party drivers: One is a full blown software app that is does not allow me to configure it the way - for example - I can my M$ mouse; the other driver link is NOT freeware - the supplier charges $20. The mouse does come with comprehensive Windows support, but for the lack of Mac support, I'm probably going to return mine.

Overall Review: Nice product - terrible marketing.

Pros: Package is *green*. No useless plastic that will end up in the trash. It's lean and mean. Installation was ok; found out that it won't work on a docking station (Dell). I plugged it in the laptop's port directly and it worked like a charm. Feels very smooth. A bit small for my hand, and I don't have big hands, but I think it's part of the adaptation. I like the DPI selection...

Cons: None for now, except that it won't work on docking stations. I'll check the support website to see if there's a way to remedy that. No biggie though.

Pros: Upright style is comfortable once you get used to it. Multiple buttons. Adjustable dpi. Tracks fine on a mousepad. Lightweight for it's bulk, easy to move around.

Cons: Scroll wheel tracks poorly/inconsistently regardless of OS settings, and has too much resistance for comfortable spinning. Cursor can drift while the mouse is perfectly still, depending on the surface... maybe my usual surface (plain white printer paper) is too bright? Button under pinky finger is too easy to trigger unintentionally.

Overall Review: Black surface areas feel nice, slightly rubberized. Buttons feel glossy-slick, which I don't mind but my coworker hates. This mouse is probably worth a lot if you've already got carpal tunnel or whatever, but as someone just using it as a preventive measure, I'm not totally happy.
