Quite durable, looks just as cool as the pictures (Owned for 2 years)
I've abused this thing quite a bit, and it's only started fraying a little bit on the top edge. By "abusing," I mean packing it with other sharp PC parts in boxes when moving several times, folding it at weird angles all the time to avoid spilling soup on it, etc. I see no signs of wear on the mat itself, and the design looks just as good as when I bought it (aside from absorbing some dirt which can be cleaned). I have never found myself needing more mouse room either. Very solid product all around.
