I also have tri-ply aluminum hard anodized, Calphalon One, and they are 15 years old now, look almost perfect. I use the 4qt dutch oven twice a week, the fry pans and chefs pan(think wok with handle) in between. They clean up beautifully with Bar Keepers Friend. They even have a large caldero (5.5 qts) and the quality is much better than the cheap ones in the store. I don’t think Calphalon makes this line now but All Clad makes a similar one, also Analon. I have several sizes of Le Creuset but I find for stove top these are lighter. I just use the roasting pans that come with the set for the oven. Hard anodized is partially non-stick without a coating that breaks down.
