Negative Positive
Title: terrible for scrolling
Review: Pros: It feels nice to use your fingers on the roller if you have finger pains from clicking so much like I do.Cons: The scrolling ring is terrible. The motion is rough. You have to first turn it some for the computer to see it then it reponds normal. Not good for small motions. I think they allowed their electrical enginners to do what they needed a mechanical engineer for.
