Great product with a competitive price, and it is truly OEM, the rough tracpoint will have a much longer life than the non-OEM copies out there which disintegrate quickly. It also has superior grip compared to the non-original versions out there. I should now have enough of the grippy tracpoints to last me 5 years, and I also now have the cup shaped tracpoints to give away since they are very nice and also good quality. The cup shaped trackpoints ones work slightly differently because they are designed to give extra leverage resulting in more of a rolling downward motion in use rather than the latteral motion of the grippy ones, but I prefer the grippy ones.

Works just like an OEM part. However, you can see slight differences in molding on the underside. It has a slightly different texture as well. Overall, a good replacement.
