Product review (5 stars): We were ready to replace our dryer due to poor performance and decided to try this product to clean ...
Our washer and dryer are on the 2nd floor of our house and the vents go to the roof where access to the vent is very difficult on spanish tile roof.  We were ready to replace our dryer due to poor performance and decided to try this product to clean the venting pipes from the opening in the laundry room.  I was HORRIFIED at the amount of lint that we pulled out of that vent piping!  It was a huge fire hazard that we were far under estimating.  Our dryer now works beautifully again the fire hazard is removed for a minimal cost.  Worth every dime.
