I bought this because I am sick and tired of buying other non stick pots and pans that only last 3 months IF your lucky with limited lifetime warranties. God forbid you make a grilled cheese in it as it totally destroyed the pan. The seen on TV is not what you get. So far I am happy with this you can use oil or butter in them and it hasn't destroyed the pan. This is the only pot that I need, it's easy to clean, it cooks evenly and I am happy. All I can say is I truly hope this lasts a long time. I hope I have found the ending to a long time of disappointment in my pots and pans.
