I use these pots for my achievements at home robot (no yogurt), especially for small pots baby. They are of good quality and durable, are dishwasher safe, which is convenient. Goodies: the date is indicated on the pot, using a "smart" cover (turning the lid until the correct date is displayed), and they are screwed. The least they are not completely waterproof. After leaving a small pot on the grass about 1 hour, then I found ants inside.
