Product review (5 stars): Excellent product.
This product is amazing. It has been taking me 2,3,4 hours to dry a small or medium size load of clothes even after replacing my old dryer. Today my husband used this to clean the vent and after he did it I had a large load of laundry including 4 or 5 heavy towels dry in 1 hour.  I recommend it for anyone having problems with drying times.  The amount of lint he got out of the vent was astounding, we are lucky we never had a dryer fire.
