I purchased these as a gift for my mother-in-law who saw mine and wanted some like it. Overall, they are very durable and have held up well. The seals sometimes come out and can be hard to get to stay back in. otherwise, I'm very happy with them. I prefer metal to plastic due to chemicals and to glass because I'm clumsy and tend to break things! I've had mine for a few year and other than the seals falling out they are great.
