I could not really believe that the Drahtlosklinkel this affordable price range works so well and I would have given all the stars ... However, the plug or its attachment in the housing prohibitively poor !!! Already at the second re-plug the connector contacts moved into the housing. Thought good can indeed times happen in one device and have just bad luck that it hit me .... However, two of these wireless ringing bought and then checked right at the Second plug and lo and behold ... with light finger pressure on the plug contacts slip the plug contacts even with this ringing in the housing. What to do ... send back? Since I have to do with technology, I opened the case and find that the plastic pins in the connector contacts are besfestigt with a screw is designed so weak that it is no wonder then that when already a slight pressure on the plug contacts of this spigot breaks and thus hiking the connector contacts into the housing. I have my two self-repaired ... (disadvantage:.. Now I can no longer return the two :-( respect, this defect and a possible further if this innerhlab the warranty period) In summary, I have to vote on only one star set, because such a misserable version of the plug-splitter mount must not be brought to the people.
