  • 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.

  • 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

  • 1/2 Impact driver

Great product and very solid. The sockets are heavy duty sockets and will break every bolt. I would buy this impact driver again.

  • It’s strong enough for most car nuts
Size: Basic Version 520 Ft-lbs
It worked very good used it to take off my water pump it wasn’t strong enough to take off the tire nuts but I didn’t really wanna break the gun so I didn’t go hard only thing I hate was it came with a clip on the 1/2 head I had to take off but it’s good for car repairs
