I needed to rotate my tires on my truck. The shop that put the wheels and tires on last had crazily over tightened the lug nuts. I couldn't break them loose even with a cheater pipe on a tire iron - so I bought this. After installing the connections with teflon tape (besides the air compressor, that is the only item you need to provide yourself with this kit) it broke the lugs loose no problem. Even if that is the only job I ever use it for, the cheap price was justified as it was as much as a tire rotation service at a shop.
