Product review (5 stars): Highly Recommended - the perfect solution
We recently bought another house and were very disappointed to learn that the clothes dryer would probably need to be replaced because it took HOURS to dry anything in it.  But thankfully - before shelling out the money for a new dryer - my husband determined that the pipe going from the dryer to the rooftop vent was completely full.  However, he could only suck out a small amount of the clog with the shopvac at the beginning for the pipe and the rooftop opening was too small to do anything with the other end.

I found this item by googling solutions on the internet.  I read all the reviews and ordered this online from amazon.  We taped all the poles together  to keep them from separating (as other reviewers suggested), and this thing worked like a charm.  Loved it!  And LOVED that I didn't have to go buy a new dryer yet.

I highly recommend this item.  The only drawback might be the price of the extension poles if you need them.  They are ridiculously expensive.  But if your pipe is 12 feet or less - this is the PERFECT solution!
