This site sucks. The so called scientific matches are crap. They just keep sending matches regardless of your criteria preferences.They are much more expensive than other sites, totally un-resposive to any complaints and if they are more than 30% successful I'd be very surprised given that at least half the matches I've received were from limited free trials. Save your money, go to a local bar and have a drink instead, at least if you don't find a date you'll have gotten out of the house!
