  • Good quality
great tool and good deal
Reviewed in the United States on September 4, 2025 by Angel Gonzalez Quinones

  • Great buy for the cost
The impact worked great for removing castle nuts and ball joint bracket bolts. The right angle is a little slow but also worked well.

  • Well Made
This was exactly what I needed for replacing my vehicle's wheel bearings. Strong, well made, and comes with a small bottle of oil. It removed all bolts, including stubborn rusted ones, with ease! For those who may be wondering like I was: yes, this will work without issue with a 6 gallon compressor. I did all 4 wheel bearings, including removing and replacing all lugs, running on a 6 gallon compressor. The included ratchet is a nice bonus. Highly recommend this for all do-it-yourself types! ... show more

  • Great value
You get a lot for your money and the impact wrench is very durable, but I gave 4 stars because there are some disadvantages. The ratchet wrench is slow and weak; almost useless, and the impact wrench sometimes gets stuck and just blows air. Besides that it works great.

  • Great Air Tools
This impact driver along with the air socket driver is a best buy in my view. Two of the handiest air tools I have. Highly recommended!

  • Worth having if you work on your own vehicles
Have a few older vehicles that require maintenance and repairs. These tools definitely help with that job and paid for them selves in one use for what I would have paid in labor to a mechanic.
