I have had my set for over 5 years. I use them 4-5 days a week. I cook for a family of 5 and my pans still look as good as they did when I got them. Even though they are dishwasher safe I hand wash them. The inside/non-stick is as good today and the first day I used them. I can take a paper towel and wipe my pan clean with almost anything I cook.
