Review on 🖱️ Durable XXL Gaming Mouse Pad, 31.5"x15.7"x0.12" Extended Size, Waterproof Non-Slip Base with Stitched Edges for Home Office Gaming Work by Kenny Davey

Unlike other large mouse pads, this one didn't straighten up after a day or so. Otherwise the product appears to be as described but I suspect it has been rolled and shredded for some time stored at high temperatures. As a result, the rubber pad is constantly deformed. If they can't improve their quality control, don't try to save $2 or $3, spend a little more on other great mouse pads with more reviews.
