Logitech MX1000 Laser Mouse
 

I was hoping the performance would at least come close to living up to what seemed like marketing hype in the published features, and the Logitech MX1000 far exceeded these expectations. The performance and precision were not only better than any other wireless mice I have tried, but as good as (or perhaps better than), high end corded mice I have used.
