The surface is too slippery (soapy), therefore no exact, precise mouse control is possible. Too rough, so you destroyed very quickly the glider (feet) of the mouse. Price too high for it. Product description is exaggerated, for example: "Eliminates microbes on contact" and even with what the surface is made to drink because there? or: "Keeps resistant as long as the mouse pad is in use," is probably burned into the surface! And if it's not even in use? Well, yes plastick not rot. Return is not worth it, because shipping costs more expensive than goods value. Offer does not go, I can not do that to my best friend (or enemy).
