Product review (4 stars): Clear Hose, Can't Lose
Thought this would fix the issue of my dryer not doing its job.  It didn't.  But I learned how to clean my dryer hose.  Apparently, you're supposed to clean it at least once a year (oops).  I will definitely do that from now on.  I wish that the bristles were a bit more condensed.  I feel like that would do a better job scraping the lint out.  But it's easily built and super flexible.  I'll keep it at close hand.
