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 expect much for the price but was still disappointed. I have a Husky 33 gallon 165 psi, 1.7hp compressor that puts out 6.8scfm @ 40psi and 5.1scfm @ 90psi. I tried several pressure settings and could stop the spin with my hand. Can't loosen lug nuts, which is what I got it for. Expensive paper weight...
