Product review (5 stars): Pays for itself the first time you use it!!
We moved into our new house about 2 years ago and needed to clean out the dryer duct. This kit made it super simple. The rods were easy to attach and very flexible, but still strong enough to spin, even when extended all 12 feet! We got out a TON more lint than we could ever imagine out of the duct!

Buying this kit and doing it myself already paid for itself. It was $150 - $200 to have a specialist come over and do the same work. Took me all of about 20 minutes to move the dryer, use the brush and all attachments, vacuum, and use disinfectant up the dryer vent!
