Product review (5 stars): Worked Well for me
I had a 15 feet vent system that was severely clogged. This tool was able to break apart dense leaves, twigs and bark. Birds must have taken refuge in my vent system for a very long time because the amount of foliage I collected filled a 13 gallon trash bag. I just purchase this home in the country and it looks like the vents where never cleaned. If this tool can break loose the foliage I had in my system, yours will be no problem!
