Reviews :
My tungstun carbide rings comfort fit ring is, cheaper, nicer looking, stronger, more durable, and more comfortable than my white gold band. But way cheaper. When I lift weights, the steel barbel doesn't even scratch the ring a bit. My previous tungsten ring, on the other hand, was trashed.
