I called them and a girl with a shrill voice answered me, she was barely able to speak english, I told her that the mouse had a problem and wasn't working, at this point I was ready to receive the request to send the old one back or at least a POP, but the only thing she said was ok no problem we'll send another one. The call lasted 30 seconds.
30 seconds worth 180 EUR.
