Product review (5 stars): Really are worth the money
We have used oven liners for a few years now.  My men folk love their pies, anyone who bakes pies knows it is almost impossible to keep the filling from dripping over onto the bottom of the oven.  Tin foil under the pie pan works, but the bottom crust does not bake well.  We really like these liners and they really are easy to clean.
