Product review (5 stars): Gardus LintEater Rocks!
Recently got a hefty estimate for our almost 25 foot vent run and looked to Amazon for a solution.  Picked up the LintEater and the extension kit after reading the reviews and followed the instructions.  Takes a little time and patience and almost too easy despite a couple interesting turns in the pipe.  Was very little lint on the brush and initially thought I had made wrong decision.  However, when I opened up my 20 gallon shop vac to discover it was 2/3's full of lint, I couldn't be more happy.  Will be part of the routine home maintenance from now on.
