The tin mixed quite well so far and is completely sealed ... but ... you can drink out of it only with the lid open and then one is the screen / grid in the way, or you always stößßt with the lips / nose off. If one takes out the sieve remains much Shake hang. You have to find a shelf for the large lattice whatsoever. I think the thing quite impractical. But as it fulfills its main function there just yet three star.
