You can confirm this with other reviews: After a few minutes you will hear a noise when the oven makes a loud bang and the pan deforms and, depending on the situation, slips out of place on the oven grate or in such a way that the Pan contents rising / moving in the air. It appears to be a heat ignition effect, and when it cools it magically straightens up again. It doesn't happen sometimes, it happens with EVERY USE. Additionally, the non-stick coating will last a MAXIMUM of 5 full uses/washes before 1) starting to stick and 2) starting to rust instantly. I also recommend for this price. Unless you require a disposable sheet. Good baking sheet 13" x 9"
