Product review (1 stars): DO NOT WASTE YOUR MONEY.
THIS VENT EXTENDER IS GARBAGE AND SHOULD BE SOLD AT A "DOLLAR STORE" BECAUSE THAT IS ALL IT'S WORTH IS $1.00.  I bought mine from Miles Kimball for 1/2 this price and will be returning them. This vent extender is the same plastic as those Red disposal plastic Party cups, so these vents are throw-away.

  DO NOT WASTE YOUR TIME AND YOUR HARD EARNED MONEY..
