The cup holds, what it promises. I prepare my tea directly into the cup to (kettle, tea bags, 5min. Pull, then close) and can him about 1 hour to fill before drinking, otherwise it is just too hot. Who wants to drink immediately, so it should fill with drinking temperature. A fall of the countertop he has already survived a small dent at the base, without affecting the properties or tightness. Very handy, I also think that the cup may in the dishwasher and that can rauslaufen nothing thanks to the high edge, even when the cup is open in the car holder. After 3 different thermo cups in the long-term test on the current state (2 months) the best!
