Product review (5 stars): Excellent product, well designed, worth the money and peace of mind
Used this product for a home we recently purchased...was built in 96 and the vent was about 12' long...worked out great for me with the extensions included.

Emptied out the shop vac before starting(smaller one) and it was COMPLETELY full after running this system through it...could be on a episode of dirty jobs if not handled correctly. Definitely use tape at connections and dryer hose to shop vac to make a solid seal...highly recommended.
