I can unfortunately nothing about the function of the device as such reports. Unfortunately, the thing was already defective at me. When I use the article but just look at me, especially the super cheap included power adapter, then to me is not really the question why that is defective. Can not imagine that it lasts a long time by myself.
Search desperately for a higher quality version, but seem to be rare here at Amazon.
Too bad, had been looking forward to it, but am now really glad to be able to return the scrap.
