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.
Good saw
Excellent saw. But the battery not work long time, need recharge.
