    • 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

    • Literally the best tool in your toolbox if you’re into anything
I use this particular tool more than anything else in my whole tool collection absolutely worth every penny I only wish I had bought one sooner. It is absolutely the best thing ever.

    • 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

    • Feels like quality.
This cordless ratchet feels like quality. Works fine but don't expect it to break loose bolts, unless they are 5/16" or smaller (IE, hex head size of 1/2", 7/16", 3/8"). However, my trusty old air ratchet isn't great at breaking things loose either, and I got tired of dragging an air hose around and constantly moving it out of the way. This Milwaukee tool has an LED to light up the work area, which I don't really need. And the light stays on about 10 seconds after you let go of the trigger. So it's more nuisance than help, IMO. Haven't had it long enough to gauge battery longevity, but I suspect the battery quality is better than the cheesy name brands . ... show more

    • Works well.
Arrived with everything as shown in the listing. Super handy to have when you have a lot of bolts to pull. Certainly not the most powerful ratchet in the world, but it wasnt designed to be, it works well for its intended purpose.
