My kids bought me the 8piece the rock cookware two years ago for Christmas. Every pot is worn (I usually use plastic utensils for stirring) . The interior coating has worn away, the bottoms are “burning” into my stove top and I couldn’t be more disappointed over their performance. I have a frying pan in my trailer that I have used for years and loved, so when I got these pots and pans I thought great. What a HUGE flop
