Great pans, heat on medium heat. Heavy but not too heavy, quality pans Easy to clean. Even cooking. Do not use spray oil on pans as instructions share this interferes with the non-stick coating. Oil spray builds up and then sticking occurs. but Olive, vegetable, any oil can be used. Interesting. I did research and found using spray oil is not for any manufactured non-stick pan. Am I the only one that didn’t know this?
