Product review (5 stars): Inexpensive and is the same as Sears provides
They are identical in shape, side and apparently composition - at almost 1/10th the price, to what Sears sent.  Sears sucks.  They are not even allowing me to return the pack I purchased from them online without collecting almost 100% of the cost including shipping and handling.  Sears shipping and handling was almost 5 times the total cost of this item purchased through Amazon.
