All-Clad has been my favorite cookware for decades (was introduced to them when I worked at one of the original Crate and Barrels in Chicago in the 70s). I noticed my nonstick saute and fry pan linings were looking very worn but I just chalked it up to lots of use. A friend in the food biz told me I should send them back to All-Clad and they'd replace them. I was dubious but called and was told if I hadn't "abused" them my friend was right. Today I got brand new replacements for my favorite pans plus they threw in a lid langiappe! Now THAT'S customer service!
