The laser seems to track very erratically on the Belkin F8E262-BLK WaveRest Gel Mouse Pad. It is so bad that the cursor jumps around making it difficult to even play solitaire smoothly. Regular Logitech LED mice have no such problem. I can use the laser mouse on a wood desktop without any problems. But it seems that the laser is TOO sensitive for the cloth surface of the mouse pad.
