Product review (5 stars): This thing is awesome
I cleaned my dryer vent in about 30 minutes to an hour. I hooked one end to a shop vac but it didn't connect cleanly to my dryer vent - nothing a little duct tape can't fix! I went through the entire dryer vent - about 25 feet (needed extensions). TIP: test the rotation of your drill by holding one of the pieces of plastic and use your drill to screw the other rod into it. Just make sure your drill is screwing one rod into the other and NOT unscrewing it. AFTER THAT DONT CHANGE YOUR DRILL DIRECTION. I don't know why others have complained that the rods came loose - they must have missed my previous tip. I actually had the opposite problem from everyone else. I had the rods screwed too tightly together and needed pliers to take them apart. Of course, if you don't have confidence in the rods you can practice on some pipes from Home Depot or you can always duct tape the rods on top of screwing them together. Needless but if it suits you. This is the first as seen on TV product that actually works - exceeded all my expectations!
