Review on Non Stick Frying Cookware Sets Lids by Lauren Naomi

I bought this pan set a little over a year ago and initially got four stars in the rating. Now I'm giving one star because the cover didn't last long. The mostly black "granite" parts opened up and exposed the interior. It also creates a rough surface, I'm not sure if that's safe. Very disappointed as this product comes from Germany with supposedly higher standards and a lifetime limited warranty. I only use used wood or food grade silicone cookware and pans on low to medium heat. The handles are not real wood either, but synthetic.
