Product review (5 stars): Great Product!
Worked great. My dryer was taking almost 2 hours to dry anything after running this through my vent system my dryer is back to normal. I love the vacuum attachment it was nice to have the shop-vac running while i ran this through my vent sucked all the crap out.

the vacuum attachment as a nice pass-thru so you can have the cleaner go up the same hole you have the vacuum on. i did it that way first then ran up to the roof and ran it back down to make sure i got all of the pipe clean. there was a ton of crap too...
