The adapter does not do justice to the many negative reviews. This is a Micro-A USB connector that does not fit naturally (or unfortunately) in Micro-B connectors. Between Micro A Micro B And there are definitely differences. In this regard, one could point out in greater detail in the product description. Otherwise, the processing and the price / performance ratio of the adapter is properly! Therefore, 5 stars! For frequent use of such an adapter, I would rather recommend an adapter cable. Because of the lever action, there is the danger that is damaged inadvertently used in mobile devices, the micro-jack.
