Product review (5 stars): The dryer now has a light on that says good airflow that was never on before
Before using this product I had used a blower to clean out 20 feet of dryer vent. Immediately after using blower i used this product and got a whole grocery bag full of lint out. The dryer now has a light on that says good airflow that was never on before.  I would recommend this to anyone with a dryer!!
