Why it works: e Harmony has an intense compatibility system (29 dimensions, to be exact), with a lengthy quiz that focuses on your long-term success as a couple.
(There is a free version, but it doesn't let you communicate with other profiles past "winking" — the Match version of Facebook poking). The gist: Speaking of being picky, Elite Singles is *the* site for those people who know exactly what they want and who aren't really interested in casual mingling.
Once you've completed your questionnaire, eharmony will provide you with matches so you don't have to browse profiles.
For some, this may not be enough freedom, but for those who aren't great at choosing partners or have no clue what they need, this may be a breath of fresh air.
And we'll just tell you now: All of the sites have free memberships, but to get the real in-depth features to find real connections with other mature singles, you'll want to have a paid account.
We've noted those price differences, as well as the differences in sign up, navigation simplicity, and the overall relationship tone of the site to help you choose the best one to fit you.
