Review on USA Pan Bakeware Quarter Sheet Pan: Warp Resistant 🍪 Nonstick Baking Pan - Made in USA from Aluminized Steel by Moussa Will

I have been using American frying pans for many years. Used for the first time today on this silicone coated baking sheet in the 425 degree oven. Resistant to warping, I don't think so, warped at least ½ inch. I have another pan from the same purchase in December 2017 that has been used a few times and hasn't warped. I can no longer recommend this product.
