This thing cuts through my 1/2" copper tubing like butter. I couldn't believe how easy it made the job. Good clean cuts in just a few turns. Make sure you tighten the blade slowly. First tighten it so that it just touches the pipe and make notches by twisting it a couple of times, then tighten 1/2 turn with each turn around the pipe. It goes by much faster than expected. And very compact, which is very good.
