I love these mice! Unfortunately, the 3 I've had all died in less than a year. I think I'll stick with the cheap ones. They don't seem to die.

It's one helluva mouse. The hyper scroll wheel is awesome.

I had the MX Revolution for school. Then I began using my home theater mouse, MX Air, for both but upgraded to this. It's a hell of a mouse even for prolonged periods.
