Product review (5 stars): Excellent product
Excellent product. Be sure to read the instructions befor use, it cleared the vent pipes well. I couldn't believe all the lint I was able to remove from the pipes. Dryer works better now. You must turn the brush to the right, clockwise at all times. The old saying righty tighty, lefty loosey definitely apply. If you try to back the brush out of the pipes by reversing the drill you may cause the sections to become separated. If you follow the directions, you will be okay. I navigated several bends with little trouble.
