I bought nuwave 2 induction cook top which love but none of my Calphalon pans were induction ready so needed to replace them. Christmas time Amazon had a sale on Emeril Pro Clad made by Al-Clad $169 set. Bought them and very happy, tri ply aluminum core stainless steal. Now if would have boughg same pans under Al Clad name the price would have been ten times more. What is the big difference since both are made by same manufacturer, only one type stainless steal and aluminum, food grade, to drastically change the price? There are pans! I did buy lot of Calphalon pans made in china over the american ones, quarter the price and worked just fine.
