The slurry can be heated directly in the cup and, if necessary, fed directly from the cup (then however, it is with a meat supplement a little crowded in the cup), the cleaning works, makes it easy in the dishwasher.
The cups are dimensionally stable, firm and take, as far as I can tell so far, even, or at least not immediately, the color of the food, eg the Karottenbreis on. Whether this occurs later sometime I do not know yet, I use the mug just in the "second round". The label I'm on adhesive labels, also because I can stick this on the cover and facilitates the overview in a freezer with drawers.
Empty can be stacked into each other and so less space than eg empty store selling glass cups.
