Summary: I bought this cordless impact to put in the toolbox of my truck. I have always trusted DeWalt tools and this is a great alternative to an air impact. It sure makes fixing a flat on the side of the road a whole lot easier and faster. The product has enough torque to loosen and tighten lugs with ease. Even my mechanic was amazed at how strong it it. The 18v battery is interchangeable with my other DeWalt tools so I did not have to buy anything different.
Summary: I live and work by my air powered impact wrench. I have of the 800 fl/lb versions that will sheer off most anything. After going through a half dozen electric/cordless ones, I couldn't find one I really liked until this one. Instant power on tap. Surprisingly good to the battery life. Works with all of the 18v batteries the Dewalt puts out.
