Product review (5 stars): You'll be amazed at the return of efficiency for your dryer too
Don't delay your purchasing decision for this.  I could not believe the amount of lint build up I had in my dryer vent ductwork.  You'll be amazed at the return of efficiency for your dryer too.  Easily cut drying times by a third if not more.  This is not even to mention the fire safety benefits of cleaning your dryer ductwork.  I highly recommend this product.
