This review is from shopping at the merchants adaptere. Unfortunately, the 4 pin mini USB connector is not used, so that the adapter OTG / host is incapable. Does that mean in my case, the tablet will not run in the Host mode to a connected USB flash drive to recognize. These would have to be bridged with the Pin4 mass. The trader pointed to that fact at the same adapter with micro USB connector also in his shop. Unfortunately, there is such a reference both in the web shop as well as Amazon for that adapter. When I asked in this regard after purchase I received the indication of an appropriate entry in the blog adaptere; pity that this notice was not given before buying. The inquiry about a possible use case for this is not OTG / host capable adapters, unfortunately, remained unanswered. According to other reviews there are obviously car radios with mini USB socket. This seems to be the only sensible application. Whether thinking of this application, the prospective landing by the Amazon search this adapter is questionable for me. At least for me (verschmerzbarer) purchase for a ton. For adapter itself: The USB socket holds quite loose the USB A connector. Sockets of a different design, as found in other OTG / Host enabled adapters act more stable. Besides the female leaves the adapter a good impression. Due to incomplete in my view description and the loose USB socket therefore only two stars.
