I've been using this site for about a month. Here is the breakdown of my thoughts and experiences with it so far. (Account creation and the browse/search features are free.)
This site has a monthly fee charge if you want to communicate. The more months you purchase at one time, the bigger the discount. If you do decide to pay, automatic renew is set to' yes.' Make sure you change it to 'no' in the billing options if you do not want it to auto renew. There are 2 payments tiers - Gold and Platinum. This is necessary for you to send messages to other members, unless they are already a paying member. Messages can be sent to anyone, however it can only be read if one of the two communicating members has a paid membership. I prefer this method over how other dating sites charge you for ever little transaction. This is a huge plus for this umbrella of dating sites. Unfortunately, membership on one site does not grant membership to their others.
There are a wide variety of members from different countries, but the overall number of members seem to be a little low compared to a few of their other sites. I've communicated with a few members, but nothing serious has come from it yet. No one has asked me for money, gifts, etc.; so that is a good thing. I, also, do not get a massive number of messages from women when I have no profile picture or information on my profile. I am not saying that this site is scam free, but they seem to have a bit of an handle on it.
Overall my experiences with this dating site have not been bad. There seems to be a lot of old accounts that have not been purged or disabled. I think they should disable accounts that have been inactive for maybe 3 to 6 months; users should be able to reactive them by logging back on. Searches come up with a lot of people that are no longer active. You may wish to sort searches by last active date just so you have a better chance of actually getting a response.
If you are interested in trying this site; I recommend you create a free account and try it out. Do not join unless you find a few souls you wish to communicate with. There is also some safety advice posted on each profile page to help you avoid scammers. Check their other sites, as most of them seem to have more (active) members. The international cupid site seems to be the most active out of the ones I've looked at.
