The cheapest vertical mouse I find. It's really a big deal. I want to buy a vertical mouse for my
mother because she get pains on her wrist sometimes when use the mouse too long. But the Evoluent is too expensive, search on amazon and ebay for a long time, just find this vertical mouse.
It's only $9.99, i can't believe it. It's cost just as the normal mouse. I don't have hesitate to
buy it. Today i received the package, it looks just as description. My mother like it very much.
If you want to get a Ergonomic Mouse, I think it's worth to try it.
