Sometimes a brace jammed something in the pliers - then something needs to be handled before it rises again.
For very tight-fitting brackets does not intervene.
The chrome coating dissolves in the used area, which is not per se bad. It is not a design item. But one gets the impression that then the pincers less accurate mesh with slight loss of functionality. Otherwise I can not explain why it initially went a bit better.
All in all, incomparably better than any other staple remover that I've used, but it is still not perfect.
