Product review (5 stars): It beat my challenge
This thing is great!

Just moved into a new house, and the dryer started taking two or three times to dry. The vent pipe is built into the wall and takes at least two 90 degree turns, and a run of nearly 6 feet. Very challenging to say the least! But not a problem for the LintEater. This was one of the easiest home repairs I've ever done. The brush pulls itself through and completely scours the pipe. Took no physical effort. The tool did all the work. It was so easy it was actually fun, and satisfying to know that it was doing the job. It is rare that a product works this good. It's as close to perfect as you can get. Buy it and don't look back!!!!
