I hesitated a while before I ordered this flask, because in the picture it did not really please me. But I have not regretted my decision: the bottle has a matt-gloss gray finish and a nice slim design - very classy! The first function test has also passed with flying colors: the practical click-lock is operated with one hand, smooth and completely sealed - and the content was at 18 (!!) hours still hot. In short: I'm thrilled!
