The carpet is very good. The picture does not fit and misled. The carpet is woven rectangular edges. That is the desired product in the description. After a year the carpet fairly resistant: a micro tear (2mm) to the unexpected outbreak of a mouse ... (sometimes it gets angry), 1 or 2 glasses of cokes reversed: it washes very well with a sponge. Do not wear under the mouse (as long as the mouse is used in normal mode, ie not projected). The carpet does not slip on the desk. As against the black cleared a little at the contact with the bottom of the palm and wrist. It depends on the skin, it often does in Ripley (well that's what Aunt Ellen told me).
