Product review (5 stars): It really worked out great!
I had a birds nest in my bathroom vent.  I ended up using all the poles that it came with it and cleaned it out.  Took me about 45 min to an hour to get it all cleaned out.  Then I worked on my dryer vent and there wasn't hardly any lint built up, but just knowing that I can do it is great!  No problems with working with this.
