Product review (4 stars): Worked well, definitely need a power drill & shop vac for proper use
Cleaned out my old vent and dryer in my new place pretty easily.  Pretty drastic savings if your only other option is to pay someone.  I really like this item and will continue to use.  Don't expect to use this item if you do not have a power drill or shop vac however, it will not work well with a regular vacuum and the power drill is a must to spin the brush.  Will use for years
