Review on 🔥 BPA & PFOA Free Teflon Non-Stick Oven Liners - 2 Pack of XL Pan Liners (17x25 inches) + Stove Top Liner - Ideal for Electric, Gas, Microwave, and Toaster Ovens - Heavy Duty Use (2 Pieces, 17 x 25) by Kenneth Mills

I was initially very happy with this product. The inserts are dark and match my electric ovens perfectly. I forgot to take out the liner when using the oven cleaning function on one of my ovens. The liner is said to be good up to 500 degrees, and that's what the oven cleaning function refers to when cleaning the oven. But the oven cleaning function works for hours. Then when I took the insert out of the oven, the coating on the bottom of the oven looked cracked/scratched. It's not cracked, it just looks bad. I'm trying to sell my house and I'm very frustrated about it. So I order another one and hide the damage the liner did. You could say this is a ridiculous review for not following the directions for leaving them in the oven with the self-cleaning feature. But you can also say this is a valid review because it says it's good up to 500 degrees Fahrenheit. It seems like something you use in the oven should last no matter how you use the oven.
