M12 Corless Hackzall, Lithium-Ion. Rated 5 by Anonymous
Nice little hackzall for working in remote areas, and attic or crawl spaces, excellent for plumber o electrical work, and any other uses like tree trimming, or any other stuff that need to be cut, without bundle of extension cords, and LED lights just what every tool need when working in low lighted area or no light at all, I use then as a flashlight and tool, lightweight, compact design, speed, and quality, all in one, and I will definitely recommend this to anyone who need to enjoy working with tools.

Junk Rated 1 by Anonymous
  No, I do not recommend this product.
The recip saw would be perfect if the motor did not burn up. Sent in the saw for repairs, and it cost almost as much as a new complete kit with case and battery's. The repaired saw has already burnt up within 4 weeks of being rebuilt. If you dont need to use it as a recip saw its great. You might be able to use it as a hammer. the 1/4' impact driver, angle drill, multi tool, 3/8" drill, 1/4" screw gun, Radio, Jig saw and 3/8" driver are good tools to buy. Dont buy the jacket either, it wont last long.

Great for small projects Rated 4 by Anonymous
As an Electrician, I bring this little guy in for service call work or the instances when I need just a few cuts. It offers terrific capability in a super small package. If you've got to cut some drywall, make a few cuts in studs or flooring, or you just need a super small tool then this is your go to recip saw. For major remodels I go to my 18V Fuel saws all. My only critisisms after a year of continual use is the amount of vibration the saw produces while trying to cut conduit and the fact that the batteries are very hard to remove from the tool. I had another trades guy tell me he has the same problem. Overall I love the tool and originally thought it would be just a toy. Definately not a toy. Based on my like for this tool I plan to upgrade to the Fuel version. Nice job Milwaukee.

Not durable Rated 1 by Anonymous
Motor burns up very easily under just moderate use. Runs but then quits working under load. This has happened twice in 4 years. Very disappointed in this Milwaukee tool. Did not expect Black & Decker performance and quality from a Milwaukee tool. Have the other M12 tools and never a problem, love them. Save your money on the Hacksaw - its not a good quality tool
