I bought this online and it is an expensive set. I thought that since she's a cook, the quality of her products would be great. I wash everything by hand. I used these for a few weeks and one day I looked down, there was grayish stuff in the food. I looked more closely and it was the Teflon!! Yuck and it's hazardous. I tried to get a refund and they said it sounded like I used metal utensils instead of nylon. I didn't use anything metal. I never got my refund.
