The seller gave the impression that the device would store in Germany. In fact, they came from China and delivery took 5 weeks. The devices were cleared incorrect, the CE mark was fake and there was no instruction manual in German. A manufacturer could not be determined. Therefore, the Customs refused entry. I can only advise them to order these devices.
Addendum: I'm waiting for 6 weeks on my money, if I'm not the worst rating would have been given, I would still pull off a star!
