Product review (5 stars): "Know It'll Get"r Done Tool"
I have tried to clean my dryer vent with other brush tools and nothing compares to this.  When I ran this brush through I had to use all of the extensions.  I didn't thing that they would stay strait but they did.  Two Walmart shopping bags worth of wet lint came out like a huge plug the first swab and blow out with a leaf blower.  I rammed the brush again and blew out with leaf blower again and more came out.  The third time the vent was all clear.  No more cheap I think it'll work tools.  I have the one "Know It'll Get"r Done Tool"!  Now my dryer drys normal again.
