Product review (5 stars): Cheap, easy to use and great peace of mind
I did end up having to buy an extra set for more poles but this is so easy to use and works as intended! We just moved into a house and it would take two full dryer loads to dry (dryer has 25 ft vent). I thought it was because of the very old and inefficient top load washer and dryer, but when I bought new front loaders, I had the same problem. I was able to push out SO much lint (at one point in the venting there was a solid blockage!) it was amazing there was not a fire in this house previously. Yikes! Although my front loaders produce a LOT less lint than the older top loaders, I still plan on taking the little bit of time to sweep this every 3 months.

Make sure you rotate clockwise only on the drill as the counterclockwise can unscrew the poles in your venting.
