Product review (5 stars): Money saver
Saved me money on getting vents cleaned and by decreasing drying time.  I was concerned that I did not have a shop vacuum for additional cleaning power.  Tried my central vacuum (too narrow) ,  but feel like it does a good job even without it.  Wished it was cheaper cause the parts themselves can't cost so much,  but it is a genius idea,  and will make my house safer from fire.
