Product review (5 stars): These brushes work great. I used them with my drill and it ...
These brushes work great. I used them with my drill and it made a world of difference for my drier vent. When you are using them, be sure to only use the forward direction of the drill otherwise the sections of rod could separate. After I had begun to remove the sections from my dryer duct, I found that I had to use a pair of pliers to turn the two sections of rod in order to separate them. After ordering the first set of rods and brush, I realized that I was only able to clean about half of the length of my dryer vent. It vents through my roof and I really didn't want to have to get up there to clean the vent so I just ordered a second kit. Even running two full sets of the rod, there were no problems encountered and now my dryer vent is remarkably more clean than it was before. I did notice that the section of duct that goes from the dryer up to the attic is a rectangle, and this brush seemed to stay more toward one side of the rectangle, so there are a few noticeable spots of lint left in the duct but it is still a lot better than it was before. Highly recommend this for anybody that wants to clean their own ducts (and avoid paying someone else to do this simple job)

I am attaching several pictures of the duct before and after, as well as the pile of lint that I got out of the duct(this pile was just what I got with the first kit before I ordered the second, so I actually got about twice this amount). You can also see what I meant about it only cleaning one side of the rectangle duct.
