Good product, Ad and in package should give more information on the thickness and heat tolerances of the pans ! The sales person had to get information from the company and yet what little is in the box was lower and different then what I was told by  your staff ,so I don't know exactly what the tolerances are or what might cause damage !
So far happy with the cookware but am concerned about future damage ....do to a lack of actual knowledge concerning the product !
