    • Makes those long days in the garage easier
This thing is a huge lifesaver. Pros: 1. Fairly narrow head, so it fits pretty well in small spaces. Not amazing, but generally pretty good. 2. Great battery life. 3. For those places where you don't have a lot of space to rachet, it's about a million times faster 4. Light is a nice perk. 5. Generally makings working on my car a pleasure Cons: 1. Low torque. You'll absolutely have to loosen many fasteners by hand, but you can finish the job with this tool. Not a huge deal. In many instances, I'm happy this has low torque, since I need to finish things off with a torque wrench, or I'm working with some fastener that has a low torque spec. 2. I feel like the head could be more narrow. 3. Having the "reverse" be on the head is sort of inconvenient. It'd be a lot better if I could change the direction on the stalk with my thumb or something. All in all, absolutely a great tool. I love it and I'll never do without a cordless ratchet tool again. ... show more

    • Durable and impressive
Not a Milwaukee fan at all, but my beloved Makita ratchet seems to be the weakest link in my Makita line up. This was the highest rated ratchet I could find and Amazon had the best price for tool, battery, and charger. It even came with a tool bag. It hasn’t had an easy life its first month in the shop, but it’s holding up. Not a lot of leverage given the size, but it fits in some tight places. Battery lasts me a day and seems to charge fast. 3/8 to 1/4 inch adapter gets more use than I thought it would. It’s not super torquey which is ok since I often use inch pounds to torque fasteners after running them down with the Milwaukee. Don’t expect to break loose fasteners on its own power. You’ll need to break them free by hand then pull the trigger. Don’t use the battery to grip, the side LEDs apparently don’t like that. Hold it just above the battery. Larger bolts like on brakes may be too much for it. You can help it along though and still be faster than a regular ratchet by hand. It’s light compared to my Makita, but that’s a 18 volt tool compared to the Milwaukee’s 12. I worry about the warranty. Most of team reds tools aren’t exactly repairable like Makita. I’ve had warranty repairs back in a week for Makita. Given the price, if I get 6 months out of it I won’t cry. Happy with it thus far. For a 12 volt tool, it has been great. Highly recommend. ... show more

Review Image by BA
I am not a Milwaukee guy and probably won’t buy another Milwaukee cordless tool BUT anyone that uses ratchets NEEDS this tool. It just plain works. I saved so much time using this thing and wish I would have bought one ages ago. It’s not fast, it’s not strong, but those are all the reasons it’s so great. For real, if you don’t have one just get one, you won’t regret it. ... show more

    • A handy ratchet for cramped fixes
The 3/8-inch drive has been handy under the dashboard, where I used it to loosen a stubborn fastener while swapping a cabin air filter. The variable-speed trigger gives me decent control, so I can ease into a bolt instead of immediately spinning it hard. I also like having the bag to keep the tool from wandering around my closet. One small gripe: the head feels chunky in the tightest spots, and I still reach for a hand ratchet when clearance gets really awkward. For the usual cramped jobs, though, it saves my wrist some effort. ... show more

    • I Love This Tool!
I purchased this ratchet after watching a video on how to replace the radiator on a 2011 Hyundai Sonata Limited. In the video, the mechanic was using the extended version of this ratchet, but I didn't realize that until after I ordered this standard version of the ratchet. It worked out just fine and made short work of replacing the radiator for someone who had never before replaced a radiator (me). The ratchet has plenty of power for removing and replacing all the bolts necessary for completing the job, and the design of the ratchet makes access into tight spaces a breeze. I highly recommend this Milwaukee cordless ratchet and wish I'd purchased it years ago. ... show more
