Product review (5 stars): Grateful to have found this.
I am grateful I found this as my dryer vent was loaded with lint. It worked as advertised. Now my dryer works like new again and I rest easy that there is no chance of a fire. I was able to come at it from both ends to get the lint out. I vacuumed it out as the directions said, but the best was to use my leaf blower and got huge chunk to blow outside.
