    good saw, not as good as the FUEL version

    Reviewed in the United States on December 1, 2025

    Verified Purchase

    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

    Reviewed in the United States on August 30, 2022

    Verified Purchase

    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.

    Great portable version of a recip saw

    Reviewed in the United States on August 17, 2024

    Verified Purchase

    I didn't realized this tool would be so useful for me. I had a full sized reciprocating saw but after using this single hand weld version, I found it so much more convenient. This is great for small jobs or for working around tight areas. I love the Milwaukee M12 line of portable tools. As a DIYer, these tools are convenient and get the job done.
    My only negative remark is that this product didn't come in its original packaging. It came in a sealed gray bag, it looked new and felt new, but I think this should've been stated in the item description. I have no problem with "Open Box" items as I've purchased them previously, with certain expectations. based on the price. This should've been labeled as an Open Box item or noted it would not come with the original packaging. This makes wonder whether these are "imperfect" or refurbished items. That being said mine worked as expected and looked new.
