Product review (1 stars): Possibly toxic fumes when heated in oven
I purchased this product to help keep my brand new oven clean.  The first time the oven was used the liners partially melted.  The coating melted off, creating a black smoke. The side of the liner that was exposed was no longer black, but a blotchy grey color when it was removed from the oven.  If it would have melted onto my oven I would have been telling this company they owed my a new one.  The yellow pyrex bowl that was in the oven turned black from the fumes and I am now genuinely worried for my and my family's health after breathing the fumes.  As far as I am concerned this product is toxic and should be pulled from the market.
