Product review (5 stars): Excellent choice to clean out the dryer vent
My house was built in 1986 and the dryer vent exits through the roof with a few twists and turns along the way. This thing attacked the built-up lint like a Texan attacking a plate of BBQ brisket. I pulled so much lint out of that pipe I was amazed that my dryer was still able to run. Air flow is MUCH better now and I anticipate shorter drying times as well.
