A small drawback is the small connector cover, directly at the beginning of the thick plug body (do not know the name and hope that my description is sufficient). This is somewhat loosely attached and dissolves over time. If the plug is pull out 1-2 times and inserting again, it may well be that you hold this coverage at some point in his hands. By simply plugging back plan, but this is quickly remedied, happened after the first of self-loosening, but still häuiger.
