Title: Poor Ring Tracking
Review: I have been using Kensington Trackballs all my life. But I was very disappointed with the tracking ring on this one. While all the other features are terrific (regular mouse tracking is great), this is no longer good enough when comparing to other devices like Apple's Wireless Mighty Mouse.I also found that the elevation of the Expert Trackball was higher and at a different angle than previous trackballs, making my wrist tired very quickly.Overall, I don't recommend this. The one I purchased I have already given away.
