If you don't have this, get it. GET IT NOW! Seriously, this is the most amazing "Mat" I have yet to use for Computing. The mat is large enough for almost two of these keyboards to fit top to bottom with an area at least as large as a regular Mousepad left over for the Mouse. The Keyboard doesn't move at all on the surface of t his mat and the Mouse works perfectly. The mat is thicker than many Mouse pads I have used in the past and seems to be made of very high quality materials. Not much else to say except for t his particular Mat you will need a decent amount of space on your desktop.
