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
Couldn't take off lug nuts on a light sedan... Even exceeding the recommendation air pressure of 90 psi. Good for well super light duty jobs. Would not recommend this ALL THESE 5 STAR REVIEWS ARE EITHER AFFLIATED OR they received this free. Listen to the 1/10 REAL people who bought this worthless junk. I would rate this junk at 50lb pounds.. The previous comment of hand clamping can stop this from spinning at Mac settings... AVOID even for simple diy people...
Replace it because present for the family I bought it again since it is an excellent product since it is given to a relative. It is one of my favorite tools and that I use the most for both my house and other jobs.
