After a short time the ridge was broken ... Well, I have gedacht..kann me indeed times happen;)
Reappointed last week. Did then combed my hair and after less than 1 minute I had already 2 parts in hand.
The quality is no longer as great as it once was, and as others have written, there were also splinter between the tines ....
I think I'll buy now what in solid wood. Definitely not recommended.
