Great little mouse pad with only a couple of drawbacks – Pressing calculator keys needs to be done slowly and with enough pressure to register because keypad is activated by pressure. The display area for your calculations and the solar panel are slightly below the surface of the mouse Pad, so you need to watch your mouse doesn't get caught going over them, though they are at the top of the mouse pad. They restrict usable space somewhat though. Otherwise; it's a clever and cute wee device and cheap enough. Has a foam backing. Surface is shiny smooth
