The appearance can scare tissue on sustainability over time but it looks really good. the mouse hovers over it without problem. size finally overcomes 15 cm by 15 cm usual and we no longer need to lift the mouse to refocus ... phew! It keeps some traces of chocolate, micro crumbs and another but by gently rubbing and a sponge, it's nickel! I highly recommend for those looking for a more ergonomically correct size mat, at very good prices and very high quality. I did not know the brand but it's really good.
