It was time to replace my 1 year old 10' nonstick frying pan that can be used in the oven (up to 500 degrees) and ran across these. I rated them 4 star instead of 5 because they're REALLY light weight. But, unlike the 12 year old pan that I'm replacing, for what I paid for these, they're economically replaceable when that time comes. I highly doubt that they'll last for 12 years (but with proper care, a couple of years, maybe).
