  • 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.

  • Great portable version of a recip saw
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. ... show more
