Only time will tell just how these hold up! So far, all is well. The non-stick surface functions as advertised. The handles are really nice and far superior to other leading brands. When washed, the lids don't seem to hold water inside the bordering rim as some of my other Calphalon lids do. We have Calphalon products dating back 15 years that we use daily, still going strong! I'm curious to see if these new products will hold up that long with all of the EPA regulations companies have to deal with today...!
