Product review (5 stars): I thought this was going to be a waste of money
Wow, I thought this was going to be a waste of money.  My wife bought it after seeing a video on FB about how much lint someone cleaned out of their duct.  I didn't think there was anyway the poles were going to bend around the corners in my ducts.  I used a drill to spin it and ran a shop vac all the time to clean up the dust & lint.  My duct's were a little longer than the 12' of poles in the package.  I just ran it from both ends and I believe I have very clean ducts now.
