I have been a member of Match.com for almost one year. I haven't found any girl which had girlfriend material but I enjoyed plenty of good dates and met dozens of nice women. Conclusion: Absolutely good dating site and I think it may be the biggest I have found.
Only reason why I stopped using it was because I found Mingle2day.com being a better site for my needs. It is pretty similar to Match.com but it was more affordable for me.
Match.com is a great dating site. Don't pay attention to all those frustrated reviewers trying to make you believe that it is a scam because it is simply not!
