Is not permitted that the articles in Germany, unfortunately I have only seen after he was with me. However alone read the processing indicate that this article may not be very trustworthy. The fed me sent adapter looked very used, and dirty looking. He corresponded in no way the image shown here. I would never use this connector.
Positive should be noted that contact by phone and email very friendly and quick with questions helps.
The article I have thrown in the trash and buy a certified connector.
