Product review (4 stars): Great value and works well
For the money this is a good kit.  The directions are clear and have good illustrations.  I also bought the extension poles in the event that I run into a dryer vent that is near the max code length of 25 feet.  I have used it on one residence for a customer and they were impressed/shocked at how much dryer lent had accumulated in their 20 year old house.  Follow the instructions and you will have great success.
