  • Use a higher level battery
Need bigger battery. I tried a 2ah battery and thought it was useless. Put A 6ah battery in and it works great now

  • good saw, not as good as the FUEL version
great hack saw for small spaces. I use it in irrigation boxes, and other tight spaces. TBH, the fuel version that I had before, is a better, stronger saw. But this one works well.

  • Good one handed operation
Needed this to work on soffits at the top of a ladder. Corded two handed Sawzall was too much risk and weight. This worked very well. It has more hand vibration than a full sized saw due to the weight. But the lack of a cord and the one handed operation are really handy. As is the small size in some locations. The short 1/2 inch stroke means that you may have to practice some sawing motions to help clear sawdust from thicker wood. Made fast work of PVC pipe in a remote location. Battery life is ok for short tasks. For all day stuff I would try to use a normal ac powered saw. Good addition to the tool box from a reputable company and at a good price. You need to already have another Milwaukee tool with identical batteries as this tool was sold in this listing without battery or charger. ... show more

  • A handy tool
This saw is small and probably not too powerful but it’s very handy to use due to it small size

  • Compact and easy to use one handed!
Awesome little lightweight, compact recip saw, great for when you can’t use two hands on a full size saw or when limited by space! As I won’t use it all that much, I’m sure it’ll last me a while.
