  • Surprisingly Powerful, Durable, and Truly “Old Reliable”
Size: High Torque 700 Ft-lbs / Pro Version
I was skeptical at first because of the low price, but this Ework 1/2-inch 21V brushless impact gun has completely impressed me. I’m restoring an old car full of rusted bolts, and this tool makes quick work of them without rounding or breaking. The torque is strong, the battery lasts, and it feels well-balanced for longer jobs. After dozens of hours of use, it’s earned the nickname “Old Reliable.” For the price, the performance and durability are outstanding. Highly recommended for anyone from DIYers to weekend mechanics. ... show more

  • Very nice tool. Worth the price.
Size: High Torque 700 Ft-lbs / Pro Version
Nice and sturdy. Heavy and solidly built. Handled removing the tire bolts with ease. Nice tool for the price.

  • Good impact gun not a lot of accessories
Size: High Torque 700 Ft-lbs / Pro Version
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. ... show more

  • Took a chance... Pleasantly Surprised!
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. ... show more
