eHarmony
When I started searching for reviews for this site I saw a lot of negativity. Most of the complaints were about the appearance of the matches or lack thereof. Since eHarmony emphasize compatibility on a personal level - a little deeper than your average single wants to go - I didn't count those reviews against them. I've seen some legitimate complaints though, like when finishing the 258 question profile 1 in 5 people are told eHarmony cannot find a match, so they're rejected. And how after your subscription expires eHarmony continues to charge your account because of an automatic re-sign up process, which a lot of people fail to notice.
Even so, I'd still give them a shot. They are thorough with 258 questions and a survey done by Harris Interactive reports that on average, 542 members marry every day in the U.S. Good for if you want science to find the love of your life.
