Product review (5 stars): Easy to use for a first-timer
I live alone and this was my first time cleaning out my dryer vents.  The directions that came with the set were very clear.  All I needed to provide was: insulating tape to replace the tape that holds the vent behind the dryer, drill+extension cord, ladder to get to the outside vent, electrical tape to reinforce the joint between extension rods, and a vacuum to vacuum up the small lint pieces.  My dryer is noticeably more efficient now.
