Product review (5 stars): Awesome!
I got these to line my gas stove top instead of using aluminum foil. I have a middle burner that is long so none of the precut liners would work. First day after lining my stove top I deep fried tacos oil splattered everywhere. Even made pools I thought for sure it would be under the liners. Pulled the burners of to clean, and after pulling up the liners nothing got below them so just a quick dip in soapy water, rinse and back on the stove they go.  I haven't had any silvering with it like some reviews but it is below the flame.  It took a little time to custom cut the holes for all my burners but so worth it.
