Product review (5 stars): Awesome product.
This dryer vent cleaning kit is great. The flexible stick attachments allow you to reach up to 12ft of length. For most homes you can clean 12ft from the inside out and 12ft from the outside in for a total of 24ft of reach. It also comes with a lint trap brush, a shop vac attachment and a few other pieces. The main 4" brush tip is great and very durable. The product itself is unbeatable and very very useful. However, it takes some getting use to. It is fed by a 1/2" chuck power drill. You have to remember to always go clockwise even when pulling the brush back out. If you accidentally go counter clockwise any time other than when unscrewing the sticks from one another, you end up with a lost dryer vent brush stuck in your duct somewhere. Take your time and learn how to use it and this tool will serve you for many years.
