"You know the adage - "If you keep doing the things you've always done, you get the results you've always gotten." That's when I got serious about eHarmony and dedicated to doing exactly the opposite of what I wanted to do, which was slow things down a lot. eHarmony certainly operates in that mode, especially as compared to Match. I had noted that situation to myself earlier, but was now ready to pay attention to changing things up a bit. Seems like it didn't take me too long or talking online with too many guys before I literally found the love of my life, who I will marry in a few months. With all that background between us already, it didn't take long for us to fall in love, and I truly believe one of the reasons was eHarmony's methodologies..." - Traveler1959 on Epinions
"On July 2, 2009, eharmony had a free weekend. I decided to get brave and see who matched. So, I saw some gentlemen who looked rather interesting including one who lived in a neighboring town about 25 minutes from me. He is my very best friend, my confident, my lover, my husband, and every dream that I dared to dream and then some. He is every prayer that I ever dared to pray and millions of unspoken prayers as well and he and I would have never met in a conventional manner. It was only through eHarmony that we met and with that meeting now comes a lifetime of happiness." - sweetcece on Epinions

Possitive Feedback
"Overall, I would say my experience with Chemistry was pretty good. I don't really care for their push on the coffee dates or their weird affiliation with Starbucks. However, I did like the fact that they sent you 5 matches per day. The matches were a mixed bag but there was enough quantity and variety to find someone I was interested in dating. I can definitely recommend the site." - modernmarvel, a user of epinions.com
"The pro of this site is that the matching system is superb. I feel that most of the matches I received were really good, unlike eHarmony who cannot grasp the concept of matching period. This site also even has a "You might also like" section for matches that were really close. I felt like this site really was able to describe me perfectly and it has a lot of great features. I also felt that it could have matched me if it weren't for really poor business practices" - J, a user of topdatingpicks.com
"Well, first of all, I need to thank them for matching me with my partner. We'd been eyeing each other for weeks on the match.com and yahoo sites but thought 'oh no, he's too this, she's too that' and neither of us made a first move although we'd each dated other people from other sites. Each of us signed up with chemistry when they were just getting started and we went through the testing and match process. We were matched within a few weeks. The chemistry.com screening questions helped me identify some traits and learn about those of potential matches in ways other sites did not." - mehitabel, a user of topdatingpicks.com
Negative Feedback
"I am deeply underwhelmed by Chemistry and will definitely not renew when my subscription runs out. Good thing I searched for promo deals and got three months for the price of one–$50 a month is ridiculous, but $50 for three seemed worth a shot." - joeymoonboots, a user of epinions.com
"No luck here. Seems repetitive in that they just send you anyone, not matched. No responses to emails. Fake profiles galore. Same old same old." - Helen, a user of edatereview.com
