I got them to keep the mouse alive the area I was using stopped working but now the mouse works just fine. There is no reason to spend a lot of money for pads when these work just fine.
These mouse pads are terrible. They permit my cursor to move horizontally but not vertically or diagonally. Had to fish my old beat up pad out of the trash so I could use my computer. I’m planning on returning them when I’m in the neighborhood. Actually they do sort of work if I put the blue surface down and work on the side with the UPC code but then the pad slips all over the desk.
