I have new tires on my car and the installer overtightened the wheel bolts. Instead of 72 ft-lbs, he tightened them to around 130. I couldn't loosen them with a 4-way wrench. That (and the Deep Well Impact socket) brought them down. I am very happy with the purchase. There are more expensive 24" breakers out there but I don't think they are any better or stronger than this one. Save a few bucks by buying this from EP Auto. You will not be disappointed. *EDIT* One thing you need to know: the screw holding the head in place may be loose - mine was VERY loose when it arrived. Make sure the screw is tight. If they don't, it can put stress on an area of the head that isn't designed to work with them, and this can fracture the head. Also, I've seen questions about using it as a torque wrench. This can be done by adding a torque wrench adapter. For example, you can get Neiko for $50 or AC Delco for around $65. It's either worth it if you want to use this, or a standard 1/2" drive ratchet as a torque wrench. Just make sure the torque band is where you need it if you're going to buy one.
