Kensington SlimBlade USB TrackBall Mouse

Pros: looks good, blah blah Cons: kensington took a good product an ruined it. Used the expert pro trackball for 10 years, now not compatible with windows 7. They recommended the slimblade. they also negleted to mention all the features and button remapping was removed. Garbage , returning today. Other Thoughts: never buy a kensington product again
