There is no trace on the support (used with a wood desk and a "standard" table) unlike my previous carpet.
It offers good maneuvering space, enough to play, work and surf the Internet.
I have used hundreds of hours at least, and there are very few traces of wear: only edges that are just beginning to take off, to perhaps 0.01 mm ... ^^
In short, a product that I recommend for its versatility, the gliding comfort, quality and durability.
