I have purchased 6 RAD pans for myself& have gifted 4 others…everyone says the same thing:” my favorite pan”-nonstick quality is exceptional, clean up is exactly as advertised-& customer service is beyond description. I had gifted my son with h the 12”,he never registered it…some months later, his son used it to sear a steak& the pan bubbled…I called RAD on a Monday morning, my file was pulled up& checked for purchase…my son’s address was requested & by that same week’s Friday, he was in receipt of his new pan-no “send a picture”-no questions asked… most remarkable. My only conplaint is that lids r not yet available or pans other than the frying pans…I would love a complete set in various sizes..
