Product review (5 stars): SUPER IMPRESSED!
We have about 25 feet of vent pipe (Dumb if you ask me).  My new dryer was not drying at all.  However, after ordering, watching videos, and reading the instructions.... I am super happy to say... HOLY COW the lint we cleaned from the vent line.  I am not kidding when I say it was literally a shop vac full.  This process did take some time, but only because of how my venting system was designed.  We did get into the attic and pull the pipes apart to continue cleaning.  And then on the roof where we found a complete blockage. We would not have discovered any of this without this tool.  I am happy to say that I love my dryer now!  It is amazing how fast things dry, and I am completely amazed at the amount of lint that we removed.

I HIGHLY recommend this product.  I promise after you see the fire hazard of lint that you see after using this product, you will be cleaning once, maybe twice a year.  My BF doubted that this product would get the job done.  Let's just say he and my dad were very impressed.
