Have the equipment bought on 28.10.2014 and on 01.20.2015 was nothing more. The manufacturer needed after all, almost 14 days for repairs. The mainboard was defective and was replaced. Warranty extension there were none. Now have I get back the unit and everything is silent. No sound when you do not even is called. 10 times Restet brings everything is nothing. Let's see how it goes. The device and the long repair time are me not even a point at the moment worth.
