I have been using my new pans multiple times per day, for about a week. Love them! Nice, even cooking and in finishing cooking meals in record time. As suggested, I only use the pans on medium or less (except for boiling water) and preheat for a minimum of 2 minutes before adding oil, and then an additional minute before adding food. If you follow these tips your pan will be non stick and cook like a dream. Best pans I've ever owned. I also got some Barkeeper's Friend to keep my new pans nice and shiny. Make sure you do, otherwise they will tarnish.
