I am extremely dissatisfied and would not recommend anyone to buy. If I could give them 0/5 stars I would. It wasn't until I had the nuts on and driven for about a week to tighten them to the correct specs that I went to change the wheels and the cheap heads came off cleanly only to loosen them. At this point there was no way to remove them - I pulled long and hard with a vise and pipe wrenches before cutting them out. I highly recommend anyone using them tighten them lightly unless you have 2-3 hours to loosen each broken nut and ruin a wheel part in the process.
