I'd like to preface by saying that I have generally found Paderno products to be of good quality for the price.
The baking rack started off great. It doesn't warp, it is effectively non-stick and very easy to clean with a cloth and soapy water. However, after several uses, the coating began to flake off, despite using in oven temps under 450°F, cleaning with a non-abrasice cloth, and never putting it in the dishwasher. I thought the coating flakes were coming off while washing, until I found bits of silvery grill coating all over the sausages I made for dinner. For this reason, I'll have to discontinue use.
I'm disappointed and hope I can find a different brand of baking rack to fit the Paderno aluminum baking sheet I had bought at the same time.
