Comfortable, lightweight and powerful

This stubby 3/8 drove impact is very comfortable to hold and use. I found it very lightweight and powerful. For what its worth I'd say it is a great tool to have for any diy or household user. I used this to to a tire rotation on my truck and it well exceeded my expectations. Good, handy and lightweight to have in a box.

Very good

I'm very happy with this 3/8" pneumatic impact wrench. It feels solid, lightweight, and comfortable to hold. The tool delivers plenty of power for removing and tightening bolts with ease. It has worked great on my vehicle repairs and saves me a lot of time compared to using hand tools. The build quality is impressive for the price, and it performs exactly as expected. I would definitely recommend it to anyone looking for a reliable air impact wrench for home or professional use.

Compact and powerful !

I used this impact to change a tire on my ATV. The power is amazing, it would easily remove the lugs from a full size vehicle. Its weight is perfect and its compact size is great. The feel and balance when using it is great. Its well built and heavy duty design makes holding it and using it a breeze. Easily adjust the power with a turn of the dial. Simple toggle buttons make it easy to switch from forwards to reverse. When installing the air hose adapter be sure to use thread seal tape.
