Product review (5 stars): These can easily be discarded once they are dirty or stained and ...
Arrived on time and are just as described.  They even included one extra package as I ordered a larger quantity.  I really appreciate that!  I immediately put them on my gas range. I purchased them as I have a family that loves to use the stove top, however, they do not always clean up after themselves and tend to have drippings and/or splatter.  These can easily be discarded once they are dirty or stained and replaced with new ones.  And it saves me having to scrub the range top every few days.  Only con is that I wish they were a little bigger to cover more area around the individual burners.  I don't know if they come in larger sizes though.
