Totally unsatisfactory. Mouse pad did not work well. The pad caused the mouse to work erratically with the cursor moving all over the place. There was glue residue left on the pad after the packaging was removed. This was impossible to clean off and remove by ordinary means. I ended up throwing the pad away.
It does keep me from getting wrist pain. But I had to speed up the mouse speed in order to keep it on the pad. My old cheaper pad controlled the mouse much better.
