Finally a Thermobecher deserves its name. The cup is very easy take apart and cleaned in the dishwasher. By one-button operation for me it is now possible mitzugeben the cup without headaches my daughter to school because the cup does not have to be turned down to be tight. Unfortunately, that was always next to the other cups. The cup does what it promises and it is really worth it to spend the money for it. The manufacturer is even a 5 year warranty on the product. I love this cup now. Cold and hot holding in the prescribed manner and leaves no wish unfulfilled. Finally a cup for left-handers and right-handers because it can be drunk from every position. You do not opt for a cover opening itself.
