we purchased a Philippe Richard set of pots and pans. We have not even used of all the pots yet. The ones we have used have all behaved in the same way. The nonstick finish peels off and rust appears on the exposed metal. Rust also appears on the outside of that spot. We are always careful to use medium heat, never high as most good cookware usually requires. We have written a letter of complaint to the manufacturer and have received no answer whatsoever.
