For mean, apparently I have big hands, the mouse is almost too small, but it fits already.

A small disadvantage but there already. If you scroll quickly to the scrolling document / website comes into Stockern. Apparently, a realization Bluetooth too slow for the amount of data.
But since I only operate office and do not play, it's not interesting for me.
