I began to use these pans the day they arrived. They're exactly as advertised, no sticking and oil really stays where poured into skillet. I especially like being able to cook at low to medium heat with these and yet get a perfect outcome always. From eggs to meats, shrimp, salmon perfecct! . The sear is great. I am very impressed and so pleased. Easy to clean. I was expecting the interior to be more bumoy or rough to sear the meat and was skeptical of the smoothness. I was so pleasantly surprised. Whatever technology has been used is amazing. I am planning to purchase other pans and or cookie trays, baking pans in Anolon X in the future. [
