We purchased 2 of these initially at the recommendation of the salesperson.  Loved them so much I added another after a few months and no after more than 2 years, We needed more sizes.  I added two more.  Mine are non stick as advertised, cook wonderfully and I do take care of them.  I keep a paper towel between pots, use non metal utensils even though I was told I could and have never had a problem I wasn't responsible for myself.
