These are probably the best pots and pans I've owned and I've been cooking for 45 years.  They truly are non stick and with careless (no offense intended) men in my family that don't pay attention to non stick pan rules, they[ve used metal utensils and not a scratch is left on the pan.  They are truly durable and non-stick.  I'm so glad I purchased them and will continue to add to this line.
