The mouse pad is too light and rigid. This makes it slip when you move the mouse. The surface is too rough. Mouse movements are thus not as fluent and silent possible as with other mousepads with a finer structure.
Update: On the bottom of the mousepad is a small sticker of HAMA. While removing the adhesive film on Mousepad remained liable. Actually annoying but by "sticks" better now on the desk and slipped less.
