Rated 4.1 out of 5 by 29 reviewers.
Rated 5 out of 5 by Very handy Love the m12 rachet. Comes in handy on the roof helping make the job a bit quicker adding just the right amount of torque. Only complaint is I wish it had an easier reverse on it instead of the old school of the old type of rachets with the spin dial. April 17, 2013
Rated 5 out of 5 by Great ratchet Excellent ratchet ,have tried snap on and chose this instead , better price and great quality October 2, 2014
Rated 1 out of 5 by Not For Serious Use. Head Breaks or Strips This thing was brilliant for a month of hard but repectful use. Then one day "POP" and it was all over. Tool still spins but not the socket.. The tool is great for spinning in and out fasteners, but NEVER attempt to use it to break fasteners loose or provide final torque. The ratchet mechanism in the head will implode. Needs improvement before I will consider getting another. I hope Milwaukee fixes this because otherwise it would be a phenomenal tool.

Rated 5 out of 5 by Great product! Very handy in tight area without cord or air hose. Half the price of snap on, mac tools, and matco for the same performance. August 19, 2014
Rated 4 out of 5 by Good - but power of a 1/4" drive ratchet Good unit. As a gauge, way less power than a pneumatic 3/8" ratchet. As long as you're not set too high on expectations for power it's a really good unit. I saw other reviews mentioning the lack of power, so I knew to expect it. I've used it a fair amount and the battery seems to last quite well. Spins loose bolts in or out fast. February 11, 2014
