I'm very happy with this ring, and it is exactly what I was looking for.  Here are highlights:
- True to size
- Very comfortable
- Nice width, not too bulky, not too thin
- Looks exactly as advertized on Amazon (yes, it is darker than white gold, and darker than my stainless steel watch band, so I agree with other reviewers regarding the darker color).
- Great style
- Very high quality, no defect whatsoever
- Highly affordable ($30 when I bought it, might be more now)

I couldn't be happier with this choice, and because it's Tungsten, I know it will last a very long time.  If I end up wanting to try a different style down the road, the $30 price will mean I won't feel guilty switching up.
