Rated 4.2 out of 5 by 88 reviewers.
Rated 3.0 out of 5.0 by good throw away tool Great tool for tight spaces BUT was denied warranty claims on both tools purchased after ONLY 2 weeks of use , claiming moisture caused issues !! February 17, 2015
Rated 5.0 out of 5.0 by This is a great saw to have . I have been looking at This Milwaukee Cordless hackzall for a few months now, when ever I went into Home Depot & I finally bought one. This is a great saw for cutting pipes, boards, Tree limbs etc. It is small enough to fit in areas that a Sawzall wouldn't & a lot easier to handle. This tool is a favorite of mine using it to saw anything it is easy to carry with with & the battiery lasts a long time. If you're even thinking about buying this hackzall, it will help you to finish jobs a lot faster then if you wear to use a regular saw, you will love having this saw it will be great to add this with the rest of your tool's.

Rated 5.0 out of 5.0 by 5year warrantee on saw and 3 year on the 4.0 battery sold me Purchased to cut small limbs and saplings, very light and have a free hand to grab limbs. Bought the 9" DIABLO BLADES ( looks like a bow saw blade) I found that using a sawing motion while running this saw makes it cut faster also purchased the 4.0 xc battery to give the saw xtra life works great. Need more power buy a chain saw but this saw is no joke. Perfect for what I'm doing and the other tools that can use this same batteries is worth checking out. I almost purchased a big, heavy and two handed reciprocating but thought about what I was going to use this for and went with the smaller lighter one. HD beat amazon on price for saw and batteries.

Rated 5.0 out of 5.0 by Excellent For Portable Cordless Reciprocating Saw... I've been a Plumbing Contractor for over 20 years and I can confidently recommend this Milwaukee product to anyone that has a light duty project. It's perfect for cutting plastic DWV (drain, waste, & vent) pipe, water closet bolts (toilet bolts), copper that's not full of water, and other cutting applications that don't require more power and a longer cutting stroke. This is NOT a 120 volt, 11+ amp reciprocating saw, so don't expect it to handle or be the proper saw for demo work, trimming hedges, pruning trees, etc. Period! If you're going to trim hedges, purchase a hedge trimmer and if you're going to prune trees, purchase a chain saw or pole trimmer.. I fail to understand all of the negative reviews this tool is getting by various reviewers. For those of you that complain about the tool seizing up or completely dying when you get water into it, I'll say this: "Read your Operators Manual. It clearly warns the operator not to allow water into the tool." This warning can be found under the Maintenance Section on page 6. I tend to agree that the battery included in this kit isn't the best one for this tool, but you can always purchase the 3.0 or 4.0 XC 12-volt battery or purchase the 18-volt version of this saw. The bottom line is: this is an affordable, durable, well-made tool that's lightweight and easy to use and handle and should provide years of dependable service if it's used as intended and properly maintained by whoever owns it.

Rated 3.0 out of 5.0 by could be better I use this saw with a grit blade for cutting plaster and drywall. The dust kills the motors and the shaft rather quickly. Milwaukee needs a sealed motor. I average a year per saw but luckily buying a bare tool is not cost prohibited. I expect more but always get less March 14, 2015
Rated 5.0 out of 5.0 by Truely an assett I purchased this saw, almost 3 years ago, as a gift for my son. The first time I used it I was disappointed. The problem was, that I was trying to use it as a sawzall, (1/2" plywood roofing) I seriously considered taking it back to the store. As our project (complete rebuild of my son's house)progressed, the value of this tool became more and more apparent. From dry light framing...this is a handy tool to have. As long as you realize that it is not a 15 amp Super Sawzall, you will love it!!! October 16, 2014
Rated 4.0 out of 5.0 by Excellent tool This, for its intended purposes, may be the most functional tool i own. Honestly, this and its big bro M18, may put reciprocating saws out of business. It will cut almost anything within reason more easily then a comparable reciprocating saw. I haven't run into any serious functional battery issues yet but individual battery pricing is absolutely absurd, costing almost as much as the new tool kit itself. This is the only reason i did not rate it 5 stars. To provide a tool this great and then shaft their customers this way seems oxymoronic to me. The good outweighs the bad, however, this is one dynamite little saw. January 14, 2014
Rated 5.0 out of 5.0 by Loved it, great for for my handicap Worked perfect for my smal project and with innability to use my left hand, it was light weight and easy to change saw blades. March 10, 2015
