Product review (5 stars): Works like a charm
My dryer vent had two turns and exited out the roof. So I headed for the attic with the drill and vent cleaner in hand.  After a short trial, I determined it was best to add each extension as it snaked down the pipe.  You wouldn't believe the lint that the vacuum pulled out at the other end!  It worked just like advertised, no mess flying around, and it took just a few minutes.  I then used the brush to clean every orifice around the dryer filter and drum.

Thanks for a great product.
