I am very happy with this platform and rest, it was perfect for what I wanted it for. I have a pull out desk and didn't have quite enough space for my keyboard and mouse. The platform gives me the space I need to comfortably use a full size keyboard (with alpha numeric keypad) and my mouse. The gel wrist rest is very comfortable as well. Well worth the money. It came with tape to stick the wrist rest down but I find it sits on the platform just fine as is, so haven't bothered sticking it down, that way I can use it separately if I ever wish to.
