Pyrex went rapidly downhill in recent years. It's glass used to be tough af. Then they changed the recipe. I haven't bothered with anything Pyrex for well over a decade because the last thing I bought inexplicably broke. There's nothing to mark it against the competition nowadays. They're just selling glass with a pyrex label.

I've heard the more expensive stuff with a blue tint is still good, the argument I heard was that they run two lines, secretly. But I've not come across any. Maybe I only shop in the shops made for poors. Or the urban myth that it still sells durable glass was another marketing scheme to trick customers into sticking with the company.

Given this anecdote, if the same company owns instant pot and pyrex, I can believe that the company partly believes that it's instant pots aren't profitable because they work. What a world.
