This is my first impact wrench. I am sure a Millwaukee is better but this gets it done for the weekend mechanic. The most this took to pop any bolt was six seconds and that was for a wheel lug that probably wouldv'e taken my who weight straining to pop it. It took a second to loosen a strut knuckle nut and another second to completely remove it. It was nothing for it to pull the splined bolt back though and tork it down. It would've taken several whacks with a hammer to drive those through.
