The edges are raised across the width
After more than a year in my possession, I find this carpet very bad.
This is due to the packaging. It comes rolled up in a box that is far too narrow. I have never been able to get a flat mat. The edges have retained the rounded/curved shape across the entire width.
I tried everything (except ironing or driving on it with my car ^^) but for office use, it's ok, but for gaming, the mouse lacks precision and when you get close to the edges, it's a mess...
Disappointed with my purchase.
