Product review (2 stars): jpg - copy and paste to see advert pic I will use as directed but am disappointed in product and will not recommend to anyone
Online picture of product shows this liner ON THE BOTTOM of the oven (beneath heating element), and the description does not warn against doing this.  Nevertheless, the instructions on the product I received said NOT to put on bottom of the oven but on the bottom rack.
