FI wants a plain black, flat style, titanium or tungsten carbide ring. I found this site and was wondering if anyone ever ordered from here, or if anyone has experience with either of these types of rings. I know they are kind of popular right now, and I've seen them priced from $35 to $500, but I'm not sire if there are any drawbacks to him wearing one of them. I know it can't be sized and he would have to order a new one if his size changed, but for this price I think I might order one in his size and one in each size up and down from his.
