Very good ergo mouse
I purchased this ergo mouse because of my painful right index finger due to mouse clicking (trigger finger). Now the clicking is done with my right thumb. Press thumb down for left click, and press thumb up on button for right click. Very simple. When I use it I have no pain in my finger and can tell my finger is slowly getting better.The only complaint I have is that the scroll button is sensitive so I find myself either scrolling too fast or putting too much effort into trying to scroll "just right." But I think the scroll mechanism can be adjusted so it's probably just me.It comes in 2 sizes. For most people, the regular size is fine. If you have really big hands you'll want the large size. It also comes in a higher priced model sans the wire.All in all I recommend this product as a viable alternative to the regular mouse.
