Best Thermobecher I know ...

... And I've tried many. Did this cup now for a few days and he is in daily use, to transport the good coffee to work. Previously, I had some cheap cups which have brought nothing in my opinion all. Either the coffee was cold very quickly or the cup was leaking.
Would definitely recommend this product further. Have him but so far only tried with hot drinks. But I think in cold content, the result is also likely to agree. Very good leakage protection (since nothing is lost), very pleasant "drinking edge" and appealing design. The bag that comes is determined good when traveling or hiking. I do not need them jeoch.
Conclusion: I know nothing better.
