After purchasing & using these fry pans, and knowing what i know now, i wouldn't have purchased these pans. It's my personal opinion they are very heavy, handles get hot and the food gets stuck in the triangles which are not smooth to the touch. The marketing of the triangle inner bottom is a cooking gimmick. I had two previous sets of Anolon cookware which were very very good, but these are junk and priced way to high, another gimmick....Also, they will not accept returns or exchanges. Another poor issue.
