Review on 🍪 GIFBERA 2-Piece Nonstick Cookie Half Sheet Baking Pan Set - Double Coating, Warp Resistant, 17 x 11 Inch by Adriana Sweet

Update 10/22/21 - the seller returned the money to me quickly, no problems. They also sent me a replacement set of baking sheets that WILL NOT warp! My originals must have been from a bad lot. This is a good company to deal with. First Review: These are heavy, durable pans that work well as baking sheets. Their main problem is that when heated in a hot oven, the pans warp a lot (about 1 inch up/down at the corners). I personally find this deformation unsatisfactory. Also, the non-stick coating is removed at the slightest touch with a hard object. So be warned. But if these disadvantages don't bother you, then these heavy baking sheets will suit you.
