Product review (5 stars): Greatest product ever!
Our dryer vent was completely clogged with a bird nest. We have second story laundry that vents out onto our roof and could not clean it from the outside because of the height and steepness of the roof.  This product easily cleaned the bird nest from the inside.  There is a "claw"  attachment included for clogs that we used first.  Then the brush cleaned out the rest of the straw and lint.  The directions were easy to follow.  We purchased the extra 12 feet extention and we definitely needed it.  It was also easier to do as a 2 person job rather that one.  We did not have a shop vac but used out regular vacuum with duct tape around the nozzle.  I cleaned most of the lint and straw out first, then went back and used the vacuum the second go around.  I can't believe how much lint came out!  It is a miracle we haven't had a dryer fire.  We will be using this a couple times per year and recommending it to our neighbors!  Thank you!
