Evoluent Vertical Mouse Right Handed - Ergonomic USB Mouse for Pain Relief & Carpal Tunnel Support - Perfect for Office, Gaming & Computer Use

I have used this mouse since the first ones were offered for sale. I by now have owned several. It is dirt cheap considering how much pain and anguish it has saved me.I use a computer for hours each day, for work and fun, and the conventional mice were causing me pain. It got to the point where my hand and wrist would still hurt even after a full night's rest! A few minutes using a conventional mouse became torture, even if I took a few days off. I feared I would need surgery to correct the problem, or that a complete lifestyle change would be needed.I tried the Evoluent Vertical Mouse in desperation, and was astounded at how much relief it brought me immediately. I instantly could use my computer normally again, and over time my painful condition corrected itself and was healed. I now can comfortably work and play for hours, with no fatigue.I learned how to use it almost instantly. It's not in any way complicated. Programming the buttons and getting used to the set-up is the only thing that might take you a minute or two.I have tried other ergo mice, and they are all in one way or another inferior. This is a high-quality device, and it is very stylish looking, too. For those who say this mouse is not good for small hands, I must retort that I have very small hands and use mine very happily.I prefer the corded version. There is a wireless, and a left-hand model, too.My one complaint: for a long time there were no 64 bit Windows drivers. I got used to the programmable buttons while using XP 32 bit, but when I upgraded to Windows 7 64, I had to use it as a two-button mouse. THIS IS WHY I tried some of the other ergo mice. I am back to using my Evoluent Vertical mouse because it truly is the best one, even as a two-button mouse. BTW I also use it as a two-button mouse in Linux, with no problems. Thank goodness 64 bit drivers are now available!The buttons are easy to press and are quiet, the scroll wheel clicks audibly but it's very quiet. I can rest my entire hand on it with no dragging, and the feet on the bottom make it glide smoothly. It's very precise.I don't know how other people define "gaming mouse", but for me this is the perfect gaming mouse, since I can't play without it. If your long hours of gaming are causing you pain, skip the other "gaming mice" since none of them are truly ergonomic. My hand hurts just looking at some of them. Just get this one and play the way you are used to: it's a true game changer because you won't tire so quickly and you will enjoy yourself more.
