I have a customer that recently got the cookware set. She emailed me the following: "I like the cookware, but the first time I used it, the skillet is all discolored on the inside. I used oil and low heat, so do not know what I did wrong. Both pans have strange spots in the bottom of them and at those spots is where you can see the water or broth start to boil. Are those areas weak spots in the stainless steel? For what the cookware costs, I don’t think I should be having this kind of problem. Has anyone else noticed this in their cookware? " Anyone have any recommendations or heard of this problem?
