Product review (5 stars): decent quality product that got the job done
My dryer has been taking longer and longer to dry a load of clothes, so I bought this kit and an extra set of rods (12 ft). The extra rods were needed to completely clean my ducts because the duct length was more than 12ft. I used a standard variable speed black and decker drill and it worked fine. I pulled at least 5 pounds of lint out of my ductwork, and the dryer takes about 30 minutes to dry a load vs. the hour and a half it was taking. This is a decent quality product that works. Total time to do the work about 1 hour from start to finish.
