At first I found the size unfamiliar. The mouse is a bit smaller than usual and the scroll wheel is really sensitive. After an adjustment period to get so but I think along well. The material does not seem to be top. Dropped my part, however, is already and it sparks more properly). But what I find particularly pleasant: When I surf for example in bed, then I use the mouse on the surface of my mattress. It does not need a mouse pad and skin still pretty good on a variety of surfaces down.
