Go on line and look up Revere Ware. There is a link. Revere ware is guaranteed for 25 years. Yes, they will replace
a worn pot. I had a frying pan replaced by Revere last year. They were nice and helpful with the replacement.
I have several pots that were my parents purchased in the 50's. I still use them.
I would not buy those cheap pots, not sure of what they are of.
