I tried a Staples Ultrathin Mouse Pad and it didn't work at all. My mouse works fine on a piece of plain white paper but the cursor wouldn't budge with the mouse on the Ultrathin Mouse Pad. I returned it within a half hour of purchasing it and bought the Staples Mouse Pad 2-Pack (50678) and that worked fine plus I have a spare for less than the price of the Ultrathin Mouse Pad.
After not using a mouse pad for years and playing games and crossword puzzles online I decided I needed to speed up my performances. I find the mouse pad has added to my speed lowering the time it takes to complete the activities I play.
