I bought the mouse on 8 October and they receive the same on October 9th! Very functional is the Kabeleinziehrolle mouse, since it is extremely convenient if you take it with! I personally do not mind the bright blue LED lamp so much, but that seems to be probably a matter of taste! However, my mouse often developed their "own life" and the cursor moves, although I do not touch the mouse! This feature proves to be extremely nerve wracking and it also stars my rating were withdrawn! But overall it fulfills its purpose for the price!
