These were to replace some I had that lasted 17 years. I hope these last as long. I find the nonstick surface excellent, and as long as you don't put them in the dishwasher, or use a metal spatula, they will last a long time. I returned one for replacement from the company after a few years when the inside started to peel. They would not replace it but gave me a $50 credit to use to purchase a new one. said I used too high a heat, and not to put them in the dishwasher. Since then, I never had a problem. Just wanted a new set.
