After reading other reviews of EHarmony, I see that users have had a wide range of experiences. Why not throw in my own two cents! I had a 6-month subscription from January-July 2008. Before I signed up, I made a note in my appointment book to contact them in late June. It was clear to me that renewal was automatice unless I shut it down, which I did.
I joined after breaking up with my girlfriend. I tried it for two months before getting back together with her.
The EHarmony questionnaire was too much work for not enough reward.
My biggest frustration was the amount of time it took to organize a date. I had email exchanges with quite a few women who seemed very nice. A few of these progressed to phone conversations. But several weeks passed and I still had not physically "met" anybody.
About five years ago I was on Match.com. Match may have changed, but my memory is that things went a lot faster. I reviewed the profiles and decided who I wanted to contact. After a quick exchange of emails, a request for her cell phone number was usually granted. If the conversation went well, a date was planned. Although it didn't result in marriage, I met and dated some very attractive - looks and otherwise - women.
Most single people dislike blind dates because they don't like trusting the matchmaking to their fiends, relatives, co-workers. Why do we think people trying to make money doing it with computers will do a better job?
