Product review (5 stars): Save $125 and do it yourself
Ok, two years ago I spent $125 for a guy to come out and clean my vents using this same kit.  I thought it looked easy to do but very messy as there was lent everywhere when he was done.  Well I just bought this one and read the instructions just to find out he did it wrong and that is why he left a mess.  I followed the instructions by hooking up a vacuum to one end and started at the other and was done with 24 feet in less than 15 minutes with NO mess.  It was so easy to do.
