Product review (5 stars): excellent
my dryer vent goes 30 ft across house, this product comes with 12 foot reach of rods, I ordered a 12 f extension kit and was able to reach most of the way, then I unhooked dryer and ran through from the other direction. This linteater works GREAT. I tightened fittings with 2 vice grips and taped with duct tape one at a time while running in the vent with dryer on. my vent has not been cleaned in 10 years (only tried blowing out with air) this thing works GREAT. unbelievable amount of lint came out. if your thinking of ordering a vent brush this works order one! Just follow directions and don't try to go high speed with all the fittings attached outside the vent (fiber glass rods will whip around and MAY brake)  you will be surprised how well it works.
