Great sawzall

Great little saw that last a good amount of time on a good battery. It will get in tight places better than the bigger ones and do just the same. I’ve had mine for a few months now and it hasn’t failed me yet. It was a great investment.

12V Just Isn't Enough

While compact, this thing will go through the 12V batteries like nobody's business, even for the lightest of jobs. Stick with the 18V version.
