I used mine for the first time yesterday and was happy with the way it worked.Drilled about 20 holes through 18" and couldn't tell that it had used any gas,Im sure a tank will get 100+ holes easily. Its the only power auger I have used so the only thing I have to compare to is an 8" mora but it starts easy cuts smooth and is fairly quiet.Hopefully I'll be as happy with it a few years dovn the road.
