The rug, too nice for Internet browsing for the game, has a very large surface area for those requiring high sensitivity and a perfect replacement for my old Razer Vespula. Moreover it is quite comfortable for the wrist, and from the view of most of the other people who used the version "control", it is not as smooth and after prolonged use, may be less comfortable than celui- above. My advice to anyone wanting a new carpet to opt for speed version careful though stack size, which can be annoying for some people. Jhésitais starting to take this version because of the impression on the carpet, it turns out that this one is much darker and "discreet" on the image.
