The only problem I had is the sizes seem to be a off a bit.  I'm typically a 9.75 and can sometimes where a 10.  I ordered a 9.5.  It was way too big, and I had to go down to a 9.  Wearing a 9 seems weird, considering I wear 10s, but the new one I got in the mail fits, but is just slightly loose.  I imagine an 8.75 would be perfect.  This is weird though, since 9.75 is normally my perfect size, and this scale is telling me an 8.75 would be my perfect size.  This 9 feels like a nice 10 to me.  The ring sizes seem to be off by one whole size, as you can see.

The ring itself is great.  I like tungsten carbide rings for their durability and style, and I like the fact that it is virtually scratch proof.  I like the brushed design of this one, with the polished edges.  I had one that was just the opposite, brushed at the edges and polished in the middle, but the polished surface smudged too easily and I found myself constantly cleaning it.  On the brushed surface, however, it is very difficult to see dirt and fingerprints, so it always looks good.
