Product review (5 stars): Works like a charm.
Worked really great. I don't see how you could navigate 90 bends by hand though. It really needs to be spun by a power drill to get around. I used my shopvac to blow from the dryer side while I worked the brush from outside. Once I got to the 3rd and 4th rod, I needed a helper to operate the drill while I worked the rods back and forth. I couldn't quite make it to my dryer with this, so I cleaned from both sides, this time using the shopvac to suck from the outside. Read the directions carefully regarding the drill and taping the joints and you shouldn't have a problem. I did the job in maybe 15 min including moving the dryer. My father paid almost 300 dollars for a pro to do this years ago.
