Product review (5 stars): a great product that does what it promises
i cant believe how easy this brush was to use and how effective it was.....i just followed the directions and with the help of my drill i cleaned out both the duct from the dryer to the wall ( which i removed first) then the one that went thru the wall then the floor and then outside (and yes it did bend easily) and left a pile of lint at the end of each one!...i would  for sure recommend this to everyone!
