Product review (5 stars): does exactly what it's supposed to do!
I live on the 3rd floor of a apartment style condo building, the builders of this building in their infinite wisdom ran my dryer vent under the concrete floor, so my dryer vent line is a big "L" shape that is a run of 55 feet long..I know "why right?", and I can't access the outside vent because the thing is 25 feet off the ground.
I had a duct cleaning company come out and give me a price on cleaning my dryer vent...they wanted $500 to rent a hydraulic lift + labor blah blah...I was like "no fricking way" so I turned to the internet which pointed me to this product, after watching countless youtube videos of this thing in action, I gave it a shot. Note to user read the directions, each rod has to be tightened with wrenches and taped, I didn't have a problem doing this but the piece of mind of it being totally secured, I had to use 18 rods..I would of hated loosing one 50ft deep in the vent. also your suppose to use it from the outside vent to the inside and while doing this have the dryer on, I had no choice but to go from the inside to the outside with no dryer vent air blowing...but I'll tell you what.... the 1st run down 55ft and then backing it out with the vacuum attachment the 4" vent hole I pulled a basketball size bag of lint out of my shop vacuum. the 2nd run down 55ft up came another basketball size pile of lint...I'm like "Ive got a lint beach ball now" Now I'm the only one in the building that has steam coming out of their vent in the middle of winter in Wisconsin. this thing slayed the dryer vent beast, I highly recommend this product. the rods are flexable the design is average, but it works. plus i used a leaf blower to make sure the job was complete.
