the cup is very well made. as the hinged Henkel proven, I will see. the isolation is quite usable only below the part is hot and that means that there heat is lost. to drink you have to cover a half turn to open and drink pretty careful, because otherwise there ne mess. Or quite agree, for he has no drinking spout ..... man can safely wrap him but in the bag, he is wiklich tight when zuschraubt him ... after a few tests -> still tight, but the cup isolated not so good ...
