Size: Basic Version 520 Ft-lbs
I don't normally write reviews but this is a great little find. Full featured with battery indicators torque indicator, work light, very compact and STRONG! Nice case and charger. I bought a larger set of SAE sockets to complement the metric sockets that come with it. Also bought a smaller set of 1/2" drive torqe limiters... which I consider mandatory since this little guy is so strong. Most car lug nuts torque specs range from about 75 to 140 ft/lbs. Overtightening past your specs could result in warped rotors or damaged wheel. For safety I recommend purchasing the torque limiting drive set. For example I use the 100 ft/lb limiter and then use a torque wrench to go to the 111 spec on my Scat Packs 6 piston Brembo brakes. I use the 120 for the rear specs and go from there to 130ft/lbs. I just used this to change blades on a 50" zero turn mower and it removed the bolts with ease. Used the 80ft/lb limiter to retighten to spec. I don't know how durable it is or how long it will last but I'm assuming this 520 ft/lb version should do well for home and shade tree mechanic work! Great value... Would recommend.

Nice and sturdy. Heavy and solidly built. Handled removing the tire bolts with ease. Nice tool for the price.

This is an excellent quality and powerful impact driver. Have had this tool for a month now and I am very satisfied with the performance and battery life. It's small enough to fit in some place other drivers will not and you don't sacrifice power for a smaller size. The tool is well built and durable it's nice to have the basic sockets to start with too. Comes with a very sturdy cell made bag to store it in. It's a winner and a keeper. I would not hesitate to purchase eWork quality tools again.

Well I like the design of the gun ie the shorter head it fits great in your hand it’s more then enough power to do anything I’m looking for , the thing I don’t care for is the bag ! It sucks I would much rather have a hard case also lack of accessories yes it comes with five ratchets, but that’s it and one battery a lot of other products out there on the market come with way then a cheep bag and 5 sockets for the price point its OK for what it is It’s 700 foot pounds per square inch but the bag and only one battery in the soft case don’t care for all of that but it is a good impact gun. I don’t know if I would recommend it.

The review I wrote below expressed my appreciation for the tool but found that one battery and no option to buy another left me no option but to return the tool. BUT I found that batteries from a Makita 21v impact tool are exactly the same as the batteries required for this tool. Amazon sells a generic version of this battery at a very good price. I cancelled my return. I am a very happy impact driver user. I returned the best impact driver I have ever used because Amazon does not have replacement batteries and does not know if they ever will. I verified that the driver does have the automatic stop run mode when breaking loose a stuck fastener. It is very high torque but light weight. It is a great value except that I can find no support on the web or at Amazon for a replacement battery or anvil. I am going to buy a more expensive, heavier driver from Harbor Freight because I can get a replacement battery. This is necessary because the tool is sold as a "Pro" model and should be workable all day. If I could buy a second battery, then one could be charging while the other is in use. I will keep watching and will buy again if a replacement battery is an option or if there is a two battery kit available.

I have had this for more than a year. The batteries hold a charge for months and the torque from the gun is incredible. I own several trailers and I use this gun to remove wheel lugs instead of hooking up and air hose. I highly recommend it.
