Product review (5 stars): Fantastic!
This deal gets the lint out of the tube...I have a 25 foot run and a lot of lint gets caught up along the way...with the extension set I am able to clean it out every six months or whenever.  One of those things, I love to see the lint blow out and get the mission accomplished.  Also very effective on getting anything else that may be stuck in there as well.  My good friend who is a Air Force Fire Chief highly recommended this set...plus it saves about $100 that the plumber would charge to clean the run out!  Great Price on Amazon and fast shipping
