Query: Only a SIMULATED mouse pad

It looks like a good mouse pad with a black rubber backing, but NO NO NO it's not. It is light as a feather and made of lightweight black foam so it will skid all around your desk. I returned them for some better ones that have the standard heavy rubber backing. Stay away from this cheap product that only SIMULATES a mouse pad. The low price should clue you in. Good pads cost $5 to $6.
