I have the seller then written, he was very accommodating and has sent the same a new me. This was now to yesterday. I tried it twice and it has held. Perhaps the other was simply incorrect, perhaps the new is soon broken, I was very careful and it's just not really stable.
The accompanying description for "complicated" hairstyles not really help me next, since they are in Chinese (?).
For the price you can probably no longer be expected, therefore, 3 stars.
