Product review (5 stars): Work as promised
Follow the DVD instruction and manual then you are golden.  I have no problem cleaning out my air drier docks even when all lent seems to be wet.  My dock were cloged to the point only small amount of air can pass through.  Thus I think it cause the drier burner temp gage shut off heat prematurely.  Clothes are drying double if not triple amount of time.  And also this cause the low temperature and humid air output then later cause existing clogged lent to become wet as well thus clogged up some more.  This kit clean it all OUT ~~~!!!  Even with the wet and compacted lent, it has no problem to spin it loose.  Due to our home construction the dryer exouse dock is locate further then 12 feet from external vent and the lent were wet.  I had to use the provided vacuum adapter to SUCK on one end then repeat on the other end to clear out the whole pipe.  In the end, I have successfully clear out the dryer vent without calling the costly professional dock cleaner and gotten a cudos then used it on going out watching the game with the boys in the afternoon ^_^
