Product review (5 stars): Buy this you can't go wrong !!
Have about an 11' long dryer vent pipe that has a couple of pretty good bends in it and this product is flexible enough to make the bends and did a wonderful job of clearing a huge almost scary dangerous amount of lint. I have to give it 5 stars because I have now gone around to a few of the elderly folks in my area and cleaned their vents too. Its amazing the amount of lint that builds up. Wonderful product.
