This is my first time using cooper pots and pans. Even though these are non-stick pots and pans I still used butter and oils when making my food.I can't say if the food sticks or not without butter. I only been using them for a week so far its scratch free. I loved that it is easy to clean!! The one thing you have to be careful with the handles get hot that would be one thing I didn't like but other then that it's is a good set.
