This item met my expectations completely. I quickly skimmed the instructions and went to work. If mechanical things are not common sense to you, please take time to read the instructions completely, or you might lose pieces in your vent pipe. Our house was built in 1964, and has a semi-permanent vent on the roof. The brush cleaned this very well, since I could not go from the exterior vent, I had to go completely from the inside of the house. This was okay, with one of my older kids helping me with the drill (and clear instructions NOT to switch the direction switch on the drill). This product was well worth the price.
