I have had and used this tool dozens of times over the last few years, it is great! I offroad with my FJ Cruiser and swap the tires/wheels every time I go out. I ALWAYS use this impact and it has never let me down. Once I had a flat on the trail and someone comes up with a Dewalt cordless impact which couldn\'t do the job, all the guys laughed when I brought this bad boy out and I just showed them a thing or two. It comes with the standard 4 lug sizes which is handy cause my two wheel sets use two different lug sizes! I just flip the socket over and go. Also, this works with standard 1/2\" sockets too. Plus I know after three clicks my nuts are torqued properly without worry for the trail ahead.
