No complaints; perfect carpet for intense gamer and office. After several months of use, no complaints are in as: I ordered a second (for my desktop computer) following extensive testing with my gamer computer. My mouse and Razer ROCCAT glide beautifully on it. So level price / quality no complaints. Caution S size is ample. In short: Nothing wrong with it does NOT skids on the desktop, it is wide enough, sliding and opaque to a gamer. And in addition it has the mouth. Like many others, I recommend it.
