Product review (5 stars): Sturdy liners
These liners are sturdy (I have had oven liners prior to buying these.  One melted and that is why I wanted to purchase a quality product) and appear to be just perfect for my oven.  No thin material in these!  I placed my liner on the bottom rack as their directions instructed.  So far, so good!.  And they cost less than it would be to purchase them in a regular store.
