Product review (5 stars): Great item does what it says. You don't know how much lint accumlates in your dryer exhaust until you clean it.
I live in a residential single family home in Florida. I have a dryer that has a vent which blows the dryer exhaust out the top of the roof.
My dryer performance for drying clothes was on the decline, and I figured it was time to clean the hose which connected to the exhaust pipe running up through the roof I also from time to time would get on the roof to clean the lint from the exhaust exit flap. I figured for the price I should try to clean the entire pipe by using this Cleaning system.

It was easy to use and I could not believe the amount of lint I pulled from the pipe, it was unbelievable. Enough to fill a large wet vac.

This tool is easy to use and works great with a drill. I'm very pleased with the purchase and now my dryer is working great again.
Definitely one of the best purchases I've made. You can't beat the results for the money.
