Product review (5 stars): WOW, works great!
The purchase price of the kit, extra extensions and bag cost me much less than one professional cleaning. After buying this on Amazon, I used it and filled the optional bag about a 1/3 full when finished. It had been about 2 years since the last professional cleaning. Additionally, using this is just as easy as any of the videos on youtube indicate and the results are perfect. The best news, now, the dryer loads are drying much quicker, especially heavy loads like towels and jeans.

Buying parts at my local hardware store, I devised a setup that also allows me to use the dryer pressure and run the brush from inside to outside. I used this for my daughters second story laundry room where it is not safe to climb to the outside vent. Worked great.

You won't go wrong on this purchase.
