Product review (5 stars): Great tool for the DIY maintenance of a dryer duct!!!!
Read about the easy use of this product and had to try it out.  I read the directions throughly before starting to know what to expect.  Be sure you do as well.  I was aware that my dryer duct work had been in use for about 8 years without any internal cleaning.  I was amazed at how much lint was clinging to the interior of the duct work.  I basically had a fire hazard waiting for the right (hot) conditions.  This came with 12' of flexible rods which was nearly the length of my duct run.  I was able to get my arm into the duct opening inside my house to pull out the amount that had clumped up together(from the rotating brush moving part of the lint forward).  From directions, to assembly, to use and clean up, I managed to get done in an hour.  I would strongly recommended this to anyone who has a home.  I am so grateful that this was available to save me $ from a professional service.
