Now my only, but, at least I think, important point of criticism. The closure is kept very simple. If you look at the plastic thread, you can see some shortcomings. I have also made the water test and of course, the water ran out. Say, the can is far from aroma-tight, because definitely comes through the air. But maybe that's just nagging at the highest level, because the part is anyway always have to open in order to refill. And yet I would have expected a bit more quality at a flavor can.
