Product review (1 stars): More misleading advertising
Where in the description of this product does it say it cannot be placed on the oven floor?  This means that I have to carefully place food on the lower oven shelf without disturbing the liner, since the instruction, once I received the item, is that it be placed on the bottom oven shelf, not easy to do in a hot oven.  This essentially makes the lower shelf useless once the oven is hot unless I remove the upper shelf first to PLACE the food on the shelf, as sliding it would not work.
Where in the description of this product does it say the fumes would kill birds in an oven temperature exceeding 500 degrees?  How can this NOT be unhealthy for humans and other living things, as well?
This was a complete waste of money and all the time I spent doing what I thought was research into a product that appears, in theory, to be a practical aid in the kitchen.  I am completely disgusted.  Rate this one a MINUS five stars.
