If I hadn't thrown it away, I would upload photos. Not only does it not untangle the hair, but it also breaks and easily damages the teeth

Excellent, it is somewhat heavier compared to the others and at first this concerned me but ultimately it helps greatly with detangling the hair. It helps more than lighter ones I had for years and I was satisfied. It doesn't break the strands because it falls gently downwards, with its own weight, without having to pull it with the strength of the hand and getting tired.
