Are you skeptical about dating sites & their compatibility reports?

I know of a woman who wanted a classy partner. She decided on an agency called parship. She paid about two hundred dollars. She took a compatibility test. She found her new man this way. She is very happy. He has a doctor`s degree, makes decent money and they feel like soul mates. She says she would have not met him in real life as he is a small man and she wanted basically a bigger and better looking man. But by writing long emails first they got to know each other and when they met this was not a problem any more. I myself do not have used an agency. But I found the story she told me very interesting.
