Positives:
- Size of the cup (small to begin with and great for later)
- Closability (Previously the lids do not fly routes, as reported by some, I would fill the cup but not up to the top)
- Stackable (both filled and unfilled state, therefore extremely space-saving)
Neutral:
- Spoon (Due to the variety of spoons that has not been used)
Negatives:
- The wear and tear described by many, I regret to confirm. This slight bubble formation on the inner walls of the cup is also produced by us. I assume that it has something to do with the acid in the mash. We no longer use the cup now but also to warm up in the microwave, but Thaw the cup overnight and fill it before we put it in the microwave to another vessel. I assume that there is an effect similar to "normal" microwave bowls. Here you have this slight "defective" for the preparation of tomato sauce, etc. But for us it's not a problem, even to dispose of one of the cup, after a certain period of use.
I recently ordered 10 new large cup in the other, even from Avent. Since I am otherwise very satisfied with the cups. Caution only with the "new" and "old" models here do not always fit the cover on the cup.
