Product review (5 stars): Well made and works well for cleaning dryer vent
This is a well made dryer vent cleaning tool that works.  My dryer vent goes from the wall down into the concrete pad, underneath my kitchen, and out to the patio.  Lots of twists and turns.  I was able to get the Gardus all the way through the vent using a regular power drill as I applied a little pressure to the rods.  I ran the cleaning tool through the dryer vent twice to get as much crud out as possible, and was pleased with the results.  You can snake about 12 ft with this tool.  The brush attachments are designed well and captured almost all of the lint in the vents.  There is a longer brush head for cleaning the dryer, and a wider and shorter head for cleaning the vent in the wall.  Also includes an adapter so you can connect a vacuum to the dryer vent and suck any remaining loose material out.  Includes everything you need to clean out the dryer vent, and anticipates most situations you might face.  Well designed and worth the money.
