Product review (1 stars): Beware of this product
I baked some potatoes last night and was very thankful when one burst that the oven liner was there to make the clean-up easy, or so I thought.  Then one of the potato pieces that fell onto the liner started to smoke and burn (oven temperature was 400 degrees), and there was a noxious odor.  Then my eyes started to burn and water.  The food was removed shortly thereafter, but when I attempted to remove the liner to clean it, there was a large white spot in the middle of it that clung to the bottom of the oven.  I had to tug to get it out and when I did, the surface of the liner under the white spot had burned onto the bottom of my new oven, leaving a permanent stain.

Needless to say, I threw the liner out and considered myself lucky that it did not start a major fire or that I was not more chemically compromised than I was.  This product is not only a complete waste of money but, in my opinion, downright dangerous.  It should be illegal to sell this.  If I could give it five MINUS stars, I would.
