Product review (5 stars): Worked very well
We have a 15' long vent that needed cleaning and, in short, this system worked very well! Just a couple notes: 1) follow the directions! The instructions tell you not to add the next rod until the prior rod is 2/3s of the way into the vent. It might look easier to try to connect 2 or 3 rods to your drill and then attempt to feed the whole thing into the vent, but that does not work! The rods are so flexible that the torque from the drill will start spinning them around like a jump rope! Just follow the directions and it works as the vendor promises. 2) The adapter for the vacuum is to fit a shop vac. So if you don't have one you'll have to use a regular vacuum. But it won't easily fit the adapter so you may need to use a bit of 2" wide tape to connect it to the end of the vent. Perfectly easy to do, but an extra step. 3) Finally, our package came with a short DVD that futher illusrtated how to do the job. Very nice touch.

In summary: Good system that worked as the ad said it would. Took me about 60 mins from when I started the job to having completed the job with everything cleaned up and the dryer back in working order.
