Review on 🍪 TeamFar Baking Sheet with Rack Set - 2 Pans & 2 Tier Racks in Stainless Steel for Cookies, Bacon, Roasting - Oven & Dishwasher Safe, Stackable and Healthy by John Hall

I'm editing my review because the seller immediately contacted me about my disappointment and refunded the money. This is still not a pan I would buy again as the pans have to withstand the heat BUT I am very happy with the customer service. They suggested preheating the pan in the oven or using it at a lower temperature to prevent warping, but I didn't have to do this with the pan.
