which also delivers what it promises! I've had some vacuum bottles, but with here can not keep them. I drink very much like tea and distributed throughout the day, my pot of tea has also long can keep hot. All possible I've tried, but none has nearly as long as the temperature kept like this one! They even allowed to in the dishwasher, for me is still a cherry on top. Of this I will definitely to buy me one or two. Very strong buy recommendation!
