This impact is light weight, well designed, does not make you fatigued after handling it all day, has plenty of power if you choose the proper air hose with high flow fittings of a minimum of .312 id. Most of these impacts are probably purchased for home use and should have little problems removing lug nuts torqued to proper specifications. I set my regulator to 110psi due to loss of air pressure created by drag inside the air lines, the air hose used with this impact is .500 min id with the smallest id .312 at the fittings. If you use a .375 diameter air hose make sure the id at the fitting connection is .312 minimum . So far very impressed !
I didn't have high expectations buying this wrench. I work at a service shop where i constantly remove tires. Straight out of the box this thing couldn't remove a single lug nut which was extremely disappointing for its advertised 400 ft pounds of torque
Haven’t used yet, purchased item to replace 25 yr old sears impact. But by all indications it should have enough torque with air compressor I have to do the job. For DIY individuals this impact is a solid buy.
