Product review (5 stars): Great product
Great product.  I ordered it after spending a great deal of time manually cleaning my oven (to prepare for Thanksgiving).  Had never heard of this type of product before doing a search on Amazon.  Arrived the day before Thanksgiving.  I put it to immediate use.  I placed one of the oven racks on the lowest level, then placed the liner on top of that.  It definately captured the overflow from the dishes I had prepared.  I took the liner out and wiped it down.  Very easy to use.  Very happy with this purchase.
