Bought a long time I used to go in the quotiends in the Uni ... How many times I would not have survived without !!! Like heat more than half a day !!!! UNHEARD OF !!! In winter I take the coffee to go in at 7am and at 16 I always hot coffee in it ... Even thing in summer you cool a little auprèalable under the tap (or put ice cubes but you lose Qty in so ...;)) you put in cold sth, and you have the whole day to sth refroidire you !!!! The seal is VERY strong, and never allowed to run anything !!! all the same there is a double safety opening when you drink ... first the Hermitian central button and a tuck to turn that opens the hole to drink. Hepatic VERY, VERY WELL THINK, VERY VERY VERY !!! ah yes, the bort that exceeds also allows you to drink more easily, as if you were drinking a simple cup ... the evil cunning can burn lip, but if you have servelles, like me, I did never burned ... TO BUY WITHOUT DOUBT
