Product review (5 stars): Wish I had these sooner!!
Wish I had these sooner!!  Our oven would always smoke up from spills and splatters so I used foil to line our oven.  That worked until I realized it had melted onto the bottom of our oven.  It was a HUGE pain to remove it, and this is exactly what I needed.  Excited to cook our Thanksgiving dinner without having to worry about spills, smoke and the clean up!
