I thought that all pieces had Thermo-Spot heat indicator and titanium non-stick coating, but only frying pans and saute pan have it. The sauce pots and large pot have regular black non-stick coating inside. I had T-fal thermo-spot frying pans before and liked them better than Calphalon, which didn't last as long as T-fal. It's a great price here for this huge set.
