The biggest problem we have with our air fryer is the mess that develops beneath the food as it cooks. It's really gross to clean up. Now, thanks to this wonderful product, we have a liner for the bottom that will soak up food drippings and help keep the bottom neat and clean. Once we are done cooking, we simply throw out the liner and replace with new ones. This is a fantastic product that works great. I will definitely buy these again and again.
