Product review (5 stars): Beautiful tool set; really works!
With a cost of about $ 30.00, this tool set for cleaning your dryer exhaust ductwork is a superb value.  I own a lot of tools and this set is outstanding for its care of manufacture and for the splendid instruction booklet that accompanies it.  Too bad my chain saw manufacturer, lawn mower manufacturer, and leaf blower manufacturer could not do so good a job with their instruction booklets.  I started cleaning from the outside exit of the dryer exhaust run, while my wife was in the laundry room with my big shop vac and the included plastic piece that makes a good seal in the transition from vac hose to 4" dryer vent.  I only needed two of the rod extensions to get to the elbow where the vent goes down from the laundry room to the crawl space.  The brush on its extensions was not too keen to make the turn at the elbow, so I went into the laundry room, turned off the shop vac, and looked down into the ductwork.  The cleaning brush was right there at the start of the elbow, so I just lowered the shop vac hose down to the brush to pick up any remaining fluff.  There was no remaining fluff--we had already gotten it all.  By virtue of comparison, I bought a $ 20.00 dryer vent cleaning kit at a local big box home building materials store.  It might have worked, but it was not made as well and there were hardly any instructions.  My Gardus kit from Amazon arrived the next day, and there was no doubt in my mind over which kit to use for the job.
