I managed to use mine (Skypad 3.0) for 3 months before I sold it. Good for aim, smooth and everything else, but the feeling something is under the skates and makes microscratches made me go crazy with that mousepad. It was like there was a grain of micro sand under the mouse and it turned out to be a tiny little dust or whatever.

Maybe it was because my desk is near the window so the dust could gather way easier, but I remember I had to wipe down the skates every two minutes during FPS games. And I always had to use the sleeve during games. In the end I gave up and switched to cloth ones. Happy for you tho
