Product review (5 stars): Easy, effective, and economical
Quick and easy to use, effective too. Just follow the directions to insure it doesn't come unscrewed in your vent (simply use two pliers to tighten, and duct tape to secure), hook it up section by section to your drill and clean away. My son's home had a 10-foot vent run that had a 180-degree bend at one end and two 90-degree bends at the other - it went through completely with no problem whatsoever. The use of a shopvac as a blower really increased the effectiveness as well. I called a chimney sweep and received a quote of $190 to clean his vent line, so this really paid for itself.
