Nonstick Ceramic Large Baking Sheet

I was very excited about this line of bakeware. after using only a handful of times the pan is stained and looks worse than cheap pans that I’ve had for years. I followed all instructions for use and even reached out to customer service to address the issues. They gave me a run around and refusing to replace or refund this product. I bought with the assumption the warranty was solid. This is just another company that wants to take your money but will not honor their warranty. I would not recommend this item or this company
