Product review (5 stars): Terrific!
I used it once and was shocked at how much lint I was able to remove from my dryer duct. Can't believe I did without this thing for so many years. Very easy to use. While I didn't do this, it might be smart to apply a small amount of lubricant to the pole section threads since it wasn't that easy to some of them from each other. I ended up using pliers to do so.
