At first, I was hooked and have the same ordered more of these beautiful to seeing storage containers that can be stacked in the fridge super. But the joy was short-lived: In the meantime I realized that accumulate in the cover between the transparent plastic and the white plastic border water and thus dirt. Happens both in the dishwasher, as well as during rinsing by hand. By leaking gaps Water runs under the edge of the lid and each time remains dirt hanging underneath, which no longer can be removed. There is of course more and more and eventually I can throw away all the doses. Unfortunately, very unhygienic. Too bad, especially at the price!
