Been mine for a few years now. There's nothing to complain about. Also great for washing with eg. a wet cloth to make it look like new.
After a total of about 5 years of use, the carpet has started to drop at the edges, and I noticed that the mouse slides better on the upper part of the carpet because that surface was used less. In addition, it is quite bad, some stains here and there, etc. after many years of use. Just bought a new one. Very affordable, 5/5 remain.
