Product review (5 stars): Wonderful invention!
We just bought a 30 year old house with about 20 feet of dryer vent that has turns and that had never been cleaned.  The previous owners had stopped using the existing vent.  My husband and I put the Gardus LintEater to the test, and it cleaned that vent comnpletly and easily.  I couldn't believe it was so quickly accomplished!  Wonderful invention!
