As already described in another review, the closure wiggles even after spinnig yet. This is the state right after purchase. After a few more uses of the closure is but (at least for us) is already over, since the plastic piece simply rotates when you turn the metal handle at the bottom - the rubber ring so therefore not compressed, so that no more bottle can be closed.
Too bad, because this was our second closure of WMF. The previous had a different principle and also a design flaw, but kept at least a little longer. Disappointing!
