They're cheap as hell and made of flimsy, soft, brittle aluminum. In the hand they feel lighter than they should. I installed them a few months ago and every time I take them off I see chips falling out. I always crank my life up to 110 foot pounds. I went to have them removed yesterday and the hex head broke off. I tried wheel lock removers and they were able to grab it because it was soft. We tried a pneumatic hammer, but even they couldn't break the eye. So right now I'm stuck on my car with a bad wheel and a flat tire until I figure out a way to get it off its stud. 1 out of 100, I definitely wouldn't recommend it to anyone I know or even people I don't like
