Delivery and Produkthaptik is good. The supplied 12V (allegedly) but switching power supply draws standby 2 watts. Also, since the on / off switch does not help. That will not do ! Alternatively, you can connect but via the rear USB port, a high-quality mobile phone charger. Result 0 watts in standby.
Update 2 days later: The seller has contacted me and asked for my problem. The short was co-ordinated with the technology and then refunded me the money. Perfect and fast service. Highly Recommended. I give for the service 1 star more.
