The forearm pad is hard and inflexible. It makes your shin sweat in about 2 minutes. The mouse pad is super slick and creates no drag which makes the mouse pointer fly over the screen.
First of all I paid a lot more than it just showed on the screen. I needed a gel wrist rest BUT you don't carry wrist rests at all - except for ones attached to mouse pads. So I bought one. The mouse pad does not stay in place and has already fallen off the keyboard drawer.
