This seems to be fairly sturdy but when it arrived I immediately knew that it would not actually be large enough to be used for its intended purpose. It is not, I repeat, is not large enough to fit over any of my saucepans to be used as a double boiler which is what I purchased it for. The description is slightly misleading. I opted to return it; however, the seller wrote a kind note of apology, refunded my money and said not to worry about returning it. I’m trying to think of something useful to do with it. Will probably end up donating it to charity.
