So then I have to say it was literally amazed Thermos. I can only recommend. The main reason: it keeps my coffee hot for more than 12 hours! It is also watertight and allows about 4 small coffee cups. Quick tip: boil water, put there in 5 min thermos, drain and refill your hot drink that will remain for 12 h. I have not tried to cool drinks, but considering how hot it holds, I have no doubt about the cold effect.
