Product review (5 stars): Cleaned out and much more educated on how to use it.
I bought this a while back and thought I used it correctly to clean out my vent, well I did not.  So I didn't think it was that great.  When I was able to retry just last week, I found that it was amazing how much Crud came out of what I thought I did clean out already.  It is really plyable and if it doesn't go in... it might just need a bit more wiggling to get through the build up.  I got a new Washer and Dryer and It kept putting up the light that the air flow was low.  So I went outside and just put on the long skinny brush and by the time I was done the dryer light was not on any more.  Successful.  I do wish it had even longer number of rods.  Mine is not really close.  The first time I used it I went from the Dryer side up and over the ceiling as far as I could.  This time I went from the outside of the house to the dryer, while the Dryer was running and it helped push all the loose particles I was creating.  My daughter called it snow in Gerorgia.
