Product review (5 stars): Gardus Lint Eater 10-piece
1) beware that you do NOT put your drill in reverse. The tool will detach.

This is a well made tool, came with very clear instructions outlining several different ways to use it, and even offering suggestions on how to improve your dryer setup. I have thin, fragile foil pipe on a long segment of the exhaust. I was careful, and this tool did no harm. A partner used a shop vac as I worked at the other end. My dryer works much better now!  And I have peace of mind re: house fires.
