Product review (4 stars): LintEater Did the job - Easy to use
My wife complained that our electric dryer was taking longer and longer to dry clothes. I ordered this Gardus LintEater system from Amazon after pricing it at my local blue & white big home improvement store where it was almost $10 more.

I used a plug-in drill at first, but the chuck wasn't big enough. My B&D 18v Firestorm drill worked fine. Used a small piece of electrical tape on each extension as I added them, per instructions, but had no problems, just follow the directions and don't reverse the drill or you will unscrew the extension.

My dryer duct goes up from the dryer to the attic and through the roof. After unplugging the dryer, I cleaned the lint trap with the included curved brush, removed the back of the dryer, removed the flex attachment to the duct, brushed out the larger pieces of lint and vaccuumed out the rest.

The LintEater got nearly two quarts of loose lint out of the approximately 10 feet of my vertical duct and was easy to use. My real problem was just above the point where the duct ended and roof vent. Lint had accumulated in this gap and rains had hardened it and eventually blocked the vent. I pulled another quart or two of hardened lint out of this gap and re-opened the vent. I used the vac per instructions to make sure the duct was clear.

I'll be loaning or renting the kit to friends. The LintEater is not made to last forever, but I'm sure I saved $100 doing this myself and with care, it could be used every year for 20-30 years. What more do you want for $26?
