Product review (5 stars): Quick, Safe, & Effective
Forget all negative reviews.  I use this kit for cleaning dryer vents in condo buildings here on the beach in Alabama & Florida. I have personally cleaned well over 1000 units with it.  I buy replacement rods and brushes as needed.  I've never had one break or get stuck unless it was my own fault.  It works perfectly every time without fail.  I use them to clean condos with runs as long as 60 feet.  This kit is everything you need to hook up to your vacuum to get a professional cleaning at 1/4 of the cost.
