From my own experience, I feel that eharmony does an adequate job of filtering out matches that would be inappropriate for me. For instance, since my religious beliefs and values are important to me and I indicated that in the questionnaire, I've received mostly matches of the same religious background. It doesn't necessarily lead to a relationship in the end, but I believe eharmony tries to match based on what the user rates as most important to him/her such as age, race, distance, religion, etc. Just keep in mind that the more criterias you place, the fewer matches you'll likely receive.

One of my complaints is getting matches who are likely inactive or non-subscribers. But I'm not sure if this is all eharmony's doing. There are probably many members out there who fail to turn off their match settings, even when they're no longer active; as such, they will continue to be automatically matched with others. However, my main complaint with eharmony is its price. Their regular prices are higher than competitor rates such as those in yahoo personals and match.com.

As for those who don't want to automatically renew and be billed for another month, cancel your membership within that same week that you subscribe. You'll still get to use the service up until your subscription expires. If you decide to renew but not pay their full price, wait to receive an offer in their discount promotions. Good luck to all!
