The roasting result I am very satisfied. Although the pan on my stove quite long does until it is hot, as opposed to a Silit-pan, which is much easier, the adhesive coating is pretty good and it can be convenient to prepare everything. However, I am very surprised how much has the pan after a few months use extreme rusting at the bottom. One can "Stainless Steel" on the ground, ironically, hardly read from rust. All my pots and pans are stainless steel and no one, except the Tefal, rust. I'm wondering if that could be a production mistake.
