The delivery came immediately. We have the cup for a few days now in use.
In fact, the Verschliesen the cup designed initially problematic. If he had to because with a lot of luck, you got him by force again. Peculiar solution for as a renowned company.
The difficulty lies in the seal of the lower part of the closure. The rubber sticks so firmly to the stainless steel beaker that it partially zuzudrehen only by force or to re-open.
But what do you do with gum, which sticks? Naturally grease. Have resorted me with olive oil or other cooking oil tasteless.
Goes wonderfully and now the cup is to close and open easily.
Also with regard to the tightness I can say nothing but good things. If as the lid is being placed and screwed. But also goes smoothly with the oil. But you should just take care, that the lid does not sit wrong.
The cup holds surprisingly well warm, or cold. Even after a long time the coffee is still edible.
Therefore, four points. Assistance for the rubber seal I would have expected from the manufacturer.
