Function perfect, very nice design.

At first I had ordered the wine and champagne closures of WMF, which I had to return again unfortunately. They looked good, but did not fit on the bottle necks. This vacuum stopper fits with its conical shape in the different thicknesses of the bottle necks, looks beautiful and up and pull the trigger of the ram he pulls out the air. The price is not the lowest, the product was also in PRC (China) manufactured, yet he works, and I will pay you some more, because this closure has probably a very long time!
