Product review (5 stars): Save your dryer!!!!
Prevent fires and keep your dryer working efficiently with this Gardus Vent Cleaning system.  Didn't realize how dirty the vents/ducting gets after only one year.  There was lint collected everywhere, from the exhaust vent of the dryer all the way through the ducting up to the outside vent grill.  Worth its cost 5x's over at the minimum.
