Well, we got our set,and being the scientifically minded family we are, we put our magnets all over our stainless steel pans. Oddly, the handles are barely made of stainless steel, (we wanted a lot of stainless steel there so that we could hold the handles without them getting too hot too fast) the sides are not made of stainless steel at all (we wanted steel there, it is not good to eat too much aluminum) and the bottoms were heavily made of stainless steel. (Don't want that much stainless steel there, too much stainless reflects heat and causes poor conduction!) So our pans were totally not what we hoped for in the way of construction. Going to find another maker.
