Edit: A week later, it is already so far the first loose contact at said location is spreading and only after 2 weeks. A very sobering result. I try it with another cable
The contact is very friendly and has sent me a new cable on the same day, if it has a better quality and durability, I will comment on that :)
Addendum:
The new cable is broken at the same point again. It was this time more attention to the ordinary accommodation. Unfortunately, the cables have the problem, that's the kink too hard and causes the cable break occurs at this point.
Otherwise a very good cable - provided that it is used for stationary use only.
