Product review (5 stars): GREAT Product
First Thing:  READ THE DIRECTIONS!! These oven liners go on the bottom rack if your oven does not have an exposed coil.  I installed my liners on my oven's bottom rack and it has worked perfectly.

The negative reviews clearly show to me that they did not follow the directions and placed them directly on the bottom of their oven.  You can only do that if your oven has an exposed coil.

I highly recommend these liners and I am pleased that I took a minute to read the directions BEFORE installing them
