Apple Pie Helper

I was walking through the Christmas Tree Shop and came across an item that I didn't know existed.  It's called a Pie Crust Shield.  One of the issues with the apple pie, that I made, was the crust burned.  The directions called to put small pieces of aluminum foil around the edges for 10-15 minutes, I did, but it still burned.

Pie Crust Shield…$1.99

This shield would be placed over the pie crust before placing in the oven.  The directions for the shield states that the shield should remain on the pie for the duration of the bake time.  To achieve a slightly browned crust, remove the shield 10-15 minutes BEFORE completion of the cooking time.

The directions on the Pillsbury Pie Crust box stated to remove the shield after 10-15 minutes, and for the remainder of the 40 minutes, there would be no shield.  No wonder it burned.

Has anyone experienced the burning of the crust?
