Product review (5 stars): Real Review From a Regular Dude
This was a life saver....literally. My g/f bought a house and it came with a brand new dryer. The dryer was taking 2 hours to dry a regular load. After some investigating I discovered the previous owner had installed a booster fan within the dryer vent duct that was not rated for moisture. The fan died causing a massive clog of lent over the years leaving a dangerous fire hazard. After removing the dead fan this tool performed as expected and then some. It cleared the clog and cleaned every inch of the vent. Follow the instructions and you won't snap the rods at the joints. The shop vac attachment helps keep this job clean but I found it quite satisfying to see all the mess come flying out of the vent when I pulled the brush back. Just vacuum it up.
****HINT****
REINFORCE THE ROD JOINTS WITH ELECTRICAL OR DUCT TAPE. I was able to snake this tool through ducting with a sharper than 90 bend and still spin the tool with the drill.
