Product review (5 stars): Linteater dryer vent clean out
Highly recommend.  This kit works excellent.  I have a 14 foot run from the wall that goes under the floor to the outside of the house with two 90 degree bends.  The kit assembles easily and is of good quality.  The shop vac attachment worked great and vacuumed everything into the canister allowing me to see how clogged the duct really was, which was shocking to see how much stuff came out (9 years in this house and never thought about checking/cleaning this).  I was amazed and quite impresssed with how well this worked.  It cleaned the duct good as new and the dryer, which had been blowing thermal fuses and taking forever for clothes to dry)works like new now.  I highly recommend this kit, it's worth it's weight in gold.  Easy assembly, good quality and sturdy construction.  I was impressd with how flexible the rods are.  One piece of advice, follow the directions and feed the rods through one at a time into the duct as you add/screw on additional lengths of extensions.  They are so flexible that if you put them all together first and then try to put them into the duct they wrap/spin around themselves making a tangled mess.  As long as you don't spin them counterclockwise which would unscrew the connections there is no need to add the tape to the joints as recommended/suggested (a pain in the rear to add and then take off as you try to feed them in and out).  Works fine without it.  This was a great buy and saved me from a very expensive service call.
