Product review (4 stars): Works Well
This cleaning kit worked well for my dryer duct which is partial flexible duct and partial rigid metal. I didn't get too many large clods as one would imagine but it is good to know that the duct is relatively clean. I hooked up a shopvac to one end while I snaked in the brush form the other end. All in all I would recommend this item - it is reasonably durable and works well.
