I own a corsair mm200 compact mousepad, and I have been using it for about 3 months now. For the first 2 months, everything was great, the mousepad was sturdy and never slid at all. Recently, I have noticed that it has started to slide around without me applying much force at all. The mousepad has never been moved off of my desk. Could it be particles somehow getting stuck? Or is it just natural for rubber to wear away like this?
