Summary: Works great! It looks cool, has a good grip and a great price used. I bought 3 of them for 3 different computers all they all work great. If you need a great mouse don't look elsewhere because this is one is great.
Summary: I had a mouse that was ergonomically uncomfortable made by GE. This mouse is a HUGE step up in the right direction for hand comfort, but for some reason, I still prefer my old-school trackball Dell mouse from 2006. Anyways, no more hand cramps with that GE mouse, this one is built to last for years since I've been using it at work for about that amount of time.
