Ac delco g12 batteries fit perfect…so far seems like a nice tool. Will update if turns out to be crap.

I recently used this ratchet on my Honda pilot. I was impressed with the power and battery life of this tool. It is much larger than I expected, so I will have to purchase a smaller version for tight spaces. This rachet makes quick work of removing automotive bolts.

Plenty of extension, works well in hard to access locations

I purchased the 3/8 and 1/4 drive set, the operation power and speed combined is fair for price. I waited until the 3/8 failed (10months est) then I purchased a big brand from the tool truck. To this day I can swing a job with upstanding turnaround time with the 1/4 still and my name brand swivel metric sockets. Of my array of tools, still a favorite hands down. 5lbs torque short of the tool truck brand, they have power, battery life needs a new design, buy an extraKeep em clean, or they will eventually short.**Customer service needs to directly contact me,I would appreciate a replacement to my remaining broken 3/8 please

Lo uso en mecanica de motocicletas y para mí es la herramienta favorita! Mas qué EXELENTE! ✨✨✨👏👌 DUROFIX👍

I saw the Milwaukee video on here saying the Durofix wasn’t as good. But I’m satisfied with it. I don’t like that it’s but heavy and not as quiet as I would want it to be but it helped me get the job done quicker at a fraction of the cost of Milwaukee. Didn’t have to spend 200 plus more dollars. Maybe that video was done using a weak battery. My battery was fully charge and it was able to unscrew spark plugs with no hesitation! I’m very impressed Value for the money! I recommend it. It has many 5 star reviews and that’s why I bought it to begin with.

So I tested the tool on a variety of bolts, and can verify that the tool has a definite issue with both break away and tightening of bolts that are already tightened to a degree. This is because for some reason the motor will not attempt to turn from a stopped position for very long after pressing the switch. When trying to loosen or further tighten a tight bolt, the motor and equipped light will turn on for a split second, then off for a second then back on for a split second. this will repeat and you wont get anywhere.Either the battery is too weak and cannot provide the amperage for the advertised torque, or they chose the wrong motor for the device. Could also be a duty cycle safety to prevent the motor from burning out, but it prevents the tool from doing as advertised. In any case, with the way it operates the tool would not be sufficient to break free bolts not even anywhere near 65ft pounds of tightness from hard to reach spots.I have a feeling the advertised torque is not for break away at all, and is instead considering starting the bolt loose and letting tightening it until the motor stops on its own for motor protection. It will eventually be left to the old method of trying to work a standard ratchet and a cheater bar in, since this till might be too bulky to take the place of that setup.I'm considering sending this back for a refund. While not having to attach an air hose is convenient, both of my air ratchets can both break away and tighten already tightened bolts just fine. I was pretty skeptical about getting a cordless ratchet in the first place, and if this is what I can expect from one of the higher priced ones, I would rather just settle with a smaller, lighter cheapo that doesn't even have variable speed and a lower tightening torque.ADDITIONAL:So I thought maybe I just got a bad one, so sent it back for a replacement. Unfortunately, the new one does exactly the same thing. The motor does not work well turning bolts that offer I would say more than 35ft lbs of resistance for loosening or while turning. I tried on a caliper bracket bolt that had thread lock applied, and it kept cutting off before operating even 1 second. I took my air ratchet which is rated at 70 ft lbs, and while it also struggled, it did not continuously stop after it had already started turning, and is strong enough to break my wrist if I'm not careful. Thats what I expect of something rated at 65 ft lbs, but this tool wont even budge on a tightened fastener. To be fair, thread locked fasteners do tend to tighten if they are turned too fast, but still, the motor does not even try or have the power to do so. But on the same job, the tool could not break free the slide pin bolts, which were 32ft lbs, no thread lock.For what it CAN do, it should be priced less to do it. Not really worth $140, and its not suitable for any heavy duty job as its advertisement suggests. If I ever need to break a bolt free from a position where I cant hand-ratchet with this tool, it has already failed me and made me resort to normal hand tools and suffering.EDIT 2:I tried to justify using it in various situations, but the motor has constantly failed me. It couldn't even break away a small car's oil pan bolts. I had to fall back on my 1/4" air ratchet, which is advertised at 35ft lbs! It works as advertised in both directions, while this electric thing doesn't get anywhere near 35 ft lbs. They need to stop advertising this as heavy duty, as its just heavy and that's it.

Very impressed with the quality and how big it is I expected it to be smaller but it’s pretty big. They do make smaller ones but this is a nice size to have and it’s slimmer profile helps it fit well. I haven’t run out of power during any jobs so power for me has been plenty. I like the lock feature because I can lock it so it doesn’t accidentally turn on and start running in my tool bag. Keeps it from running the battery dead by accident.

The "good" about this model is variable speed, LED light, long reach, and locking feature for manual torque. You will need the locking feature a lot, because this wrench is WEAK WEAK WEAK. I have another one from another brand without the extended neck, and that one is advertised at 40 ft lbs. This one is either the same or slightly WEAKER than my short-neck model rated at 40 ft lbs. Kind of a bummer as I paid extra hoping for more power and got the same or less.The extended neck is nice, but it adds hugely to the weight which makes it more cumbersome to actually use. Handy for tight spots where you have to make lots of tiny wrench movements with any other tool, but you will have to use the lock to manually bust loose every bolt and nut first because there I don't think it will do even basic 10mm intake manifold bolts with just its own power... maybe just barely, and you will sure get tired fast of holding this weight up.I'd say 3.5 stars but not having the option to go between I'm dropping to 3, mainly because of failing to meet its advertised torque rating. If it at least had a true 65 ft lbs it would be 4 stars.
