Product review (5 stars): Does the trick!
It worked great to clean out my clogged dryer vent. There are lots of different methods to use it, all covered in the manual. The main auger comes not only with a spare set screw and the Allen wrench necessary but the instructions even specifically tells you the size in case you manage to lose both. I love the attention to detail. The vacuum adapter is a spiffy plus to suck the lint out at the auger knocks it loose.
