Product review (5 stars): Works better than expected
This thing works better than expected.  The brush and the extender rods allow the lint to be broken up and easily removed.  It should pay for itself in electricity savings by reducing dryer time.  We had allowed our dryer vent to go without cleaning way too long but once we cleaned it with the Lint Eater it reduced drying time by 66%.  Of course we will not need to use it again until drying times increase, probably a year or two.
