The only negative points are:
-Easy to deform (thin design of silver)
to repair virtually non -after deformation by the rib structure which deforms and by the filigree-building is not (very bad) can be bent into shape on the back (see item picture).
Therefore, always store chain night and do not forget else the heart can be crushed downright without being noticed.
In spite of the price / performance ratio is unbeatable and the chain worth buying anyway.
