After just over six months suddenly the motherboard does not work anymore, although properly used in the technical sense of the proposed property. This merchant offers on our message to the question of whether we want to take the warranty or the manufacturer's warranty claim. We try it first with warranty to relieve the trader. AsRock refers to this, however (RMA) on his website again to contact the dealer. From the dealer, we were told that he could not guarantee. We asked how the guarantee would react. Unfortunately we offered the dealer does not help to implement the communication with AsRock in terms of a warranty. In ensuring the trader makes only explicitly and repeatedly attention to our burden of proof. A return could not be implemented so far, as well as this, no assistance (return-shipping label has been requested). Now we're sitting here with a broken board and wait for what or what not happening now. Trusting shopping is to buy only from vendors who send at least on Amazon for us in the future. As the first-acquired motherboard of the same product series ASRock in another PC was defective, the complaint about Amazon ran helpful, the trader apologized for our "damage" and it was immediately your money back. Even with an exchange we could have lived, but so .... hm.
