Product review (5 stars): Handles even the toughest ducts
I was skeptical ordering this product because I felt my dryer duct was so unique. I live on the second floor of a four-unit building, and my dryer duct travels under my floor 20' to get to the outside. On the outside, there's about a 15' drop to the ground. The ground is also sloped, so I can't put a ladder there without digging a platform. Plus, I don't even have a ladder to begin with.

And so, I was going to have to clean my dryer duct just from the inside-out, using the 12' extension. I initially tried the wide-brush, but by the 19th foot, it got stuck. I then pulled it out, and changed the brush to the claw. When I snaked this through the duct, it punched all the way through! I went outside and I could see that the claw had taken a bird's nest with it! I then replaced the claw with the wide-brush, but again it got stuck. I finally cut the bristles on the wide brush by a third, and that finally went all the way through.

Thanks Gardus, I'm glad I didn't have to pay some pricey technician just to get my dryer working in top shape again!
