Product review (5 stars): Easy to assemble and use
Easy to assemble and use. I got about a pound of gross lint out of my dryer duct with this. I have a long duct that goes all through the kitchen so I used it inside until I ran out of room, and then went outside and went through that duct to get the rest of it. My dryer now dries faster and I don't have that burning smell anymore. Be sure to use the duct tape they recommend to hold the pieces together, as they could come unscrewed during use and make sure you secure the brush each time you put it back up in the vent. as it can also become loose from use.
