Overall, for its price, it is good. I bought it to have sterilized water for the baby and I wanted it to be glass. The truth is, it doesn't keep the water warm for a long time and it didn't really work for the purpose I wanted it for. So, three stars mainly because it's not very convenient and because I bought two and one of them must have some issue because it doesn't close properly, but okay, we will definitely use it for something else in the future.
