I met a relationship that ended up lasting a year on this site. He was true to the demographic that the site advertises (a devout Christian) which led to us considering marriage fairly quickly. Unfortunately it ended, which has nothing to do with the site. I live in a big city and had noticed there were very few guys in my area, instead they were all over the world, not at all helpful. I guess I just got lucky, but nonetheless I'd recommend the site to a fried.
Pros
I believe they are true Christians
Cons
They could build up their numbers. In a major city there should be more selection.
