I own this blanket now since one and a half years and had they been exchange four times. A few days ago it was that time again: the fifth blanket is over. You can not even say that it was constantly at the same point of failure. The first time the power supply gave up the ghost, the second time the heating coil fell ever further so that the heated area is always smaller. In the third and fourth time, the respect of the ceiling discolored yellowish / brownish along the incorporated heating elements, it emerged sporadically black scorched, so you had to be afraid to contact the ceiling, the bed on fire (which is likely to be but ruled out the safety power supply) , The ceiling was not claimed great, lay flat on the bed, did not come into contact with liquid, or the like. Nevertheless, in each case after 3-4 months a new ceiling was due. After all, the support for Beurer running smoothly and there was always promptly delivered a new ceiling. However, such quality defects are totally unacceptable for a simple blanket with the high price of just 100 euros. I'll inquire at Beurer if I get the purchase price (or at least part of) refunded place yet another new ceiling that holds only 3 months. My brother had bought the same ceiling and after nearly a year reached even in the third. The symptoms were identical. Could awarded zero stars for a product, the HD 100 from Beurer would be a hot favorite for it. From a purchase I would strongly advise against!
