I use my hands a lot and I'm hard on rings, tungsten carbide is the only durable ring metal I've ever ran across.
It fits me, I'm normally a 5.5 or so but I bought a 5 and it fits me perfectly.
I can actually wear this ring at work and not have it be scratched up or bent within a couple weeks, unlike my other rings I've had.

I would recommend this for anyone who wants a cheap durable metal for jewelry.
