Product review (5 stars): What a brilliant tool to have
What a brilliant tool to have!  Cleaning my dryer vent is a breeze with this wonderful gizmo. Plus, it involves power tools!  Dang near the most fun you could have while cleaning!  Cleans thoroughly. (Note: I disconnected my dryer from the vent and did not use the enclosed plastic protector that keeps the brush from damaging the dryer.)  My vent has two turns or bends and the rods twist and bend easily.  When using all four rods, I held the drill "backwards," pointing towards me and let the rod pass behind me to keep it from whipping around and kinking.  Once I figured that out, it was truly a simple process to get my dryer vent cleaned in no time.  Insert brush into dryer vent, turn on drill, push into vent and remove from vent while using the drill, repeat, and that's it!  Oh, so easy. Now I am just waiting for the leaves to fall and plug up the downspouts....
