Product review (5 stars): Worked extremely well... smart tool. 29' dryer exhaust vent
Worked Great!! My house has a dryer exhaust vent booster fan that was never wired in by the builder.  My house is 10 years old, when I discovered that my dryer exhaust ducts were completely clogged around the booster fan.  The dryer vent ducts looked like a clogged artery...  with about 1" of lint along the walls of the duct work.  My vent has two 90 degree turns and spans about 29" to exit the roof. I started in the attic and seperated the duct work by the booster fan. With the extension pack, I was able to clean going both directions.  The Lint Eater tool worked extremely well, and is very smartly done.  I hooked a shop vacuum on one end and turned on the dryer.  The amount air flow created to suck the lint out was tremendous. Follow the instructions and the tool will work exactly as intended. At first I thought the brush was small, but realized that helps make the turns through the duct work. I used electric tape on rods and tightened the rods finger tight and had no problems. I clutched my cordless drill down (put dial setting by the drill chuck on 5). I ran the drill at slow speed, and then bumped it up when I felt like the majority of the lint had been removed from the section was completed.  My theory was that is wanted scrub the walls of the ducts.  I purchased from Lowes because I was desperate, but Amazon would have been $10 cheaper. I removed at least 3 gallons of lint from the dryer exhaust duct work.  Now this tool will be used once a year to improve dryer efficiency and reduce the risk of a fire.
