I have purchased these glasses before, and they are gradually replacing other ones that I’ve had in the past from a different company that have all started breaking. These are very sturdy, and I’ve yet to have one that has broken in the dishwasher or during generall use if it tips over it’s fine. I’m not saying that they will never break, but so far so good. We’ve had a lot of luck with them. And they look very pretty, especially with the indentation at the bottoms.
