Love my Heritage the Rock pt and pan set.  Clean up is so easy and I never have to scrub to get it clean.  If used properly it's built to last.  I never put the burner on max, 7 or 8 is more than enough to bring food to a boil and I always use plastic utensils so the coating won't get scratched.  Loved mine so much I bought my daughter a set  Would highly recommend to anyone.
