Product review (5 stars): Works like a charm
This works extremely well. My air pipe is 20 feet long from the inside of the house to the outside. I bought 2 kits and just attached them to make the necessary length. My pipe was completely glogged for haven't being cleaned in over 10 years. With a little elbow grease the glog came out and the dryer is working great. *Don't reverse the drill or it will come undone.
