Product review (5 stars): Best Money Ever Spent!
My husband said this was the best $20 we ever spent!  Worked as described and got a pillow's worth of lint out of the dryer exhaust in our new home.  We figure that it had never been done since the home was built almost 20 years ago.  It was taking us 1 1/12 hours to dry one load of laundry.  One cleaning with the Deflecto and now we are back to normal, putting less stress on our dryer, wasting less energy, saving time and saving money on our utility bill.
