Quite good, it leaves food at a rate according to the consumption of the animals and has a large volume, so it lasts a long time. The lid closes well, but a persistent animal may possibly open it (it didn't happen to me)

The plastic is very good, the only negative thing is that the lid does not close properly on top and a worried pet can open it. I managed to fix it with some tape, but it slightly ruins the appearance. However, it is quite large, as we left the cat with 2 liters of food for 4 days and there was still some left.
