We did a renovation installed an induction cook top. Although they say that this pan works on induction cook tops, it does not. On lever 9, the highest heat, I can boil a large pot of water in a minute with a real induction pot. With this fry pan, I can barely get the pan hot at this level - it try’s but fails. On my previous gas range, I would give the pan a 3.5 rating as it still underperforms other fry pans. I own two of these pans as have one at a winter property where we have a electric range so have plenty of experience. Their knives are perfect and their star.
