Title: I'm sincerely disappointed . . .
Review: I purchased the Kensington Expert Mouse Optical USB Trackball about 4 years ago to use on my Mac workstation. It is wonderful. I liked it so much, I recently purchased a second one to use at work on my PC.What a disappointment. The new one LOOKS like the first one I purchased, but it sure doesn't work like that one.The trackball is "stiff" - it doesn't feel like velvet under my fingertips like to older one. Maybe it just needs to be "broken in". But the scroll ring, mentioned in other reviews, is simply unacceptable. The new one feels like it has sand in it. It moves very roughly. My older model absolutely glides - like on ball bearings.If this is typical of the quality of this product, it has certainly been compromised since I purchased the original one. I don't think I can live with this. I'll probably pack it up and return it.Acco - are you listening?
