Bests & Worsts Reviews from Amazon

It specifically says on the listing and the box that if you have a visible heating element in the oven, to place the liner underneath the visible heating element on the bottom of the oven. So I did exactly as it said, and it melted the liner and left a white residue on my heating element after just a few uses (at normal baking temps, 350F-400F). Please do not waste your money like I did.
