Evoluent USB Wired Right-Handed VerticalMouse 4 is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by AC00 from Excellent Ergonomic MouseThis mouse definitely requires a bit of a learning curve, as it is completely different from any mouse I have ever used. The mouse functionality stacks vertically, rather than horizontally, which is quite the change. However, I am no longer getting any pain in my fingers, wrist, or forearms since I started using this mouse. My hand is in a completely natural position. The learning curve has been to train my fingers to access the features and functions available with this mouse. I would highly recommend this mouse to anyone experiencing this type of pain.

Rated 5 out of 5 by drwhite from Best mouse on market1. Comfort: No carpal tunnel aches and pains with this mouse.2. Use: Natural hand position makes use very easy. Same button operation as regular mouse, right click/left click.3. Options: Complete customizable, make the buttons (5 of them)do what you want them to do. Quickly change between different applications.4. I am buying my second one after just over two years of use. The wheel axis is not seated anymore, it wiggles. But that is not enough to stop me from wanting another one.
