Product review (5 stars): Better dryer performance and minimize lint fire danger all in one package.
Over the past few months the dry time of my dryer has gotten longer and longer.  And I figured out why the vent was filling slowly with lint.  I tried to clean it out with just a shop vac but even with extension hoses I couldn't get the lint buildup off the walls of the vent pipe.  Then I saw the Gardus LintEater and thought that makes sense a tool to clean the walls of the vent pipe too.  I used it and removed at least 5 pounds of lint from the pipes.  Definitely worth the price.  And now my clothes are dry after a single cycle of the dryer.
