i've tried out all these pads at a lan some weeks ago, and i can say that the funcsurface1030(http://www.func.net) is definetely the best,
- it has too surfaces (one like rough like the everglide, the other smooth like the 3M)
- it doesn't wear of nearly as fast as all the others
- it has a mouse clip
- and the best design (imo)
buy it @ http://www.everglide.com !
