AC warrantied a roasting pan for me years ago. They did a lot of complaining about how I should not have put it on the stovetop. How the heck was I supposed to deglaze the pan? anyhow, they did replace.
I have another AC piece, a skillet that has not been level since shortly after I bought it. I'm not sure whether it is warped or just unbalanced since it lists toward the handle. Anyhow, I no longer automatically assume that an AC product is first rate.
