I had initially bought the nova master for my new mouse, Cyborg RAT7 Contagion. But O rage, O despair, it was not at all, but then not at all appreciated by my mouse: erratic behavior, saccade, stall ... nothing was going. The Nova Master is not in question, but his job with RAT7 was impossible. Not wanting to prematurely wear my mouse on a wooden desk (anyway not quite smooth), so I was left to buy a second mat and not to make another mistake, I stayed in the same brand. At the finish of the tube - the carpet is rolled as it is flexible - and unpacking of the carpet, the first thing you notice is its size. It is HUGE. Anyway nova master does not half portion ... well, once unwrapped Glide, it is clear that the nova is a half portion ;-). Either place on my desk, he takes third in width, but ultimately it is not worse. This will position the mouse where desired and it always leaves room. Skiing is excellent. The design is not bad at all (that's a matter of taste but I like my side) - attention, it is darker shown on the site (but ultimately it is all the more discreet and less messy). The finish is impeccable. It only remains to see its behavior in time (and already give him flatten correctly - stay in the tube still leaves a little "waving"). In short: perfect with RAT7, great price (pity it was not in stock at the purchase of the mouse), impressive and aesthetically pleasing. AMAZON always on top for his service.
