My mouse pad is HS I decided I ordered this carpet having had pleasant views on the Razer brand and the quality of their products. At the reception a little surprised at the box carton packaging beautiful decor with the carpet rolled in. I open the box with the fear of finding myself with a rug that once out will not hold flat or make waves Even the carpet is thin 2- 3 mm thick the decor is nice black and green (I love Kawasaki) and a thermo-welded seam toured the carpet, the size is perfect for the little space on my desk (size S) and especially the wife perfectly mat shape on which it landed without wave or others. After for office use it going to perfection, I have a gamer mouse Steelseries and no acceleration signal loss or latency. And to use game (MMORPG) is top, I have not tried with FPS games. So I suggest for the price the quality and finish.
