Title: They finally did it right, again!
Review: I used to be totally sold on the old heavy duty billiard ball expert mice. However, about 5 years ago something bad happened. They cheapened the fit and finish of the ball and mechanisms. I purchased a couple but quickly passed them down to my kids. I ended up getting a AMicrosoft trackball that felt much better than the crap expert mice. Ok, all that buildup to state that 3 months ago I got my son the KEM 7.0 when his crap KEM gave out. Wow! The smoothness of the ball/pointer movement is excellent. The old feel of what I remember of the KEM is back! If you like trackballs, I can heartily recommend these! Oh, BTW, I just got my new KEM 7.0 a week ago. Every bit as nice.
