Product review (1 stars): Piece of garbage.
I wish I could have the time back that I spent trying to use each of these ineffective tools; I would have used it toward the time required to do the job right. Save your time and money; take your dryer apart and vacuum out the vent- it's a dozen bolts and 40 minutes of your time. The "universal" vacuum attachment did not fit our vacuum...all the other tools simply pushed the lint further into an area that could only be reached by removing the vent.
