I have owned all clad cookware for 40 years, cooking on a gas cooktop. I just moved to an induction cooktop and to my dismay found my older all-clad was not magnetic so had to replace it all except a sauteuse and some TK pots i had more recently bought. This D3 set replaced much of my "lost" cookware, work on induction and is wonderful. It is lighter than many of the D5 pots I had but function as well. Happy to have this set. Hope it last like my older pots that still looked like new after 40 years.
