I can only say, finally a vacuum flask that keeps its verspricht.Sie is absolutely tight, that was the main problem with many bottles vorher.Mein man takes daily coffee with the business and, until recently, had he the old pot (ca. 2 years old) are still in a bag always on safety, otherwise the mess to groß.Der coffee was really long hot, even without warming up before the bottle with hot water long. The lid as drinking cups is pretty good if you get used to the small hat.Der overhanging edge closure of the bottle is really handy. Clip and on, clip and on. It can also be disassembled for cleaning well, which is helpful. So from me there full Punkte.Mal see when the shutter gives up the ghost, but you can even buy more spare, really great! Bottle is certainly not very cheap, but if I expect what we as in the past to raise funds for it have spent .... Addendum 21:08:13: The bottle is now almost daily use. What stands out is the following problem: When the bottle is empty and you want to screw her, that's often not so easy. Since the closure of 2 parts, one often turns from the upper part and the lower part is firmly seated. And true proof! As if a vacuum in the bottle. And I can not say that the closure is mega securely screwed in Verschließen.Ansonsten everything continue as above beschrieben.Aber for this shortcoming there a star deduction. 10/28/13 Supplement to precisely what is mentioned drawback: We have now found a solution that works for 98%. If you have such. Eg the hot coffee filled. And then later want to drink the cup 1, you have to unscrew the entire closing this one time. This then creates less of a vacuum more and you can then turn off the shutter without problems.
