Product review (5 stars): Massive amounts of lent!
Oh my were my dryer ducts full of lent! Followed directions and it worked like a charm. I couldn't believe how much my wife and I pulled lint out. It cut the drying time to almost half!  I've already lent it out to friends and family to clean their dryer ducts. I think I will make it a twice a year habit to clean from now on.
