Now the negative things:
The 230V plug was loose on my unit. At first I thought that he might be flexible. Unfortunately, far from it. A plug into the socket was not possible. He has been completely pushed into the machine.
In my case, fortunately, because I do not want to see, if the case occurs the other way around. Plugging possible, but the pull out is something hanging or breaking.
Since I in such quality too scared to my devices have rather no second attempt.
