Summary: This is a great tool and I would fight you before you could take it away from me. The half inch anvil on it is tight as others have said, but I prefer it that way. I believe tightness makes stronger impact activity. Loose attachments take away from impact strength.
Summary: I was doing suspension work on my car and one particular bolt was so stuck that I decided it was about time to buy an impact wrench. Since I didn't have or want to get a compressor, I decided to go electric. This impact wrench made short work of all of the bolts I tried it on.
Summary: To work on a car this impact tool is a little heavy so depending where you need to untighten a bolt you may run into difficulties. Nonetheless it does a good job. I used it on brake caliper bolts and lug nuts, it did the job.
Summary: I torque my lug nuts no more than 80 pounds. It took them right off but so what? Well, it means, I can jack the car up then remove the lug nuts instead of braking them loose first, worth the price of admission right there. I had an axle go bad and the shop refused to torque the axle nut.
