I had a wonderful experience with eHarmony. A little less than 3 years ago I signed up for a one month subscription and extended it for one more. I would receive several matches every day. Yes, there were many matches that did not respond ut there were quite a few that did. I ended up meeting 5 of those matches and one of them became a very special person in my life. Our relationship was as close to perfect as one could be. Unfortunately, he was diagnosed with cancer about 10 months into our relationship and passed away a few days short of 2 years from the day we met. I would never trade those 2 years for anything in this world.
That was 9 months ago and I am again thinking of using eHarmony. You do have to weed throught a lot of matches but in my case it was well worth it. and if I do decide to use the service again, it is because I had such a good experience the last time.
