Product review (5 stars): Easy to use
The product works as advertised.  It is very easy to use and the instructions are well laid out and easy to understand.  Our run was longer than the rods could clean from one end but I just ran them through from the other end to finish the run.  Our run is made of rigid pipe and includes 2 90 degree bends.  When I was finished, the shop vac was completely full of lint.  Prior to using this product we had to run our dryer on the hi setting to dry our clothes and more often than not it took more than one cycle to dry our clothes (granted we do run loads that are pretty large).  But since cleaning our duct, we can run our dryer on med and get the loads dry in one cycle.  Pretty amazing if you think about it.
