Product review (5 stars): A must have
I should have bought this years ago. When connected to a decent drill you can really remove a ton of lint/debris. I cleaned out easily a pound of lint starting from my dryer all the way to the outside vent cap. Using this cleaning kit has made me rethink the use of certain fabric softeners which can leave a tacky residue on the inside of exhaust pipes thus catching and trapping lint the filter misses.

Note: be aware of what direction your drill is spinning. If your drill is spinning counter clock wise you may inadvertently loosen the extension rods from each other thus leaving the brush stuck several feet down the pipe (whoops). This is not a design flaw just the nature of tightening and loosening.

Pro's My dryer is more efficient: Faster/Less power used. My dryer is much safer to use now.
