I had this set for about 3 months now and the difference is incredible. I was using the non coated baking pans before but never-more! Anything I bake comes out great, I'm yet to burn another batch of cookies and what a breeze to clean! Even baking a ham (in the big baking pan, great size by the way) was easy to do and to clean up. Can't tell you how long this set will last, but so far it has hold up really good with moderate to heavy usage. I can assure you that if this set ever needs replacement I would do so without even thinking about it, it is now a must have in my kitchen.
