I have tried several battery operated and air impact wrenches, none of which could do the job effectively. This impact wrench removes and installs wheel lugs on my pickup (140 ft/lbs of torque) with ease and with dial set at only half power. This has made my life much easier as I have a bad back and pulling on a lug wrench is no longer easy for me. Now I can rotate my own tires again! I would recommend this product to anybody looking to speed up their work and make life easier.
