I signed up for three months and here are my experiences.
1. They advertise as a site for highly educated people. Most "matches" suggested for me had high school or community college educations. Some had grade school. I'd say less than 25% had bachelor's degrees or higher.
2. They advertise as a site for professionals. There were a few physicians, lawyers or college professors. Most were salespeople, project supervisors, and even some truck mechanics.
3. There were few matches with people within 75 miles. They offer about 20 "wild card matches" a day. These matches were people from as far as 600 miles away.
4. Their headquarters are in Germany. If you have a concern you can call an international number during German business hours or try to complete an online form, which doesn't appear after you click the link to it. The link to the form doesn't work.
5. They alerted me very quickly of two scammers they identified. One was obvious to me, the other not.
6. One of the profile questions is whether you'd be interested in children. A large portion of men over 65 said either "yes, of course" or "maybe in the future." The site is for people over 50. Not sure where they expected the children to come from.
7. There were lots of matches whose hobbies were fishing, bowling, and motorcycle riding.
8. I had one extended "conversation" with a match. He eventually told me he had a history of relationship problems. He then told me I wasn't a very pleasant person and stopped writing.
I guess I wasn't expecting much so disappointment may be a strong word, but I'm not signing up again.
Bottom Line: No, I would not recommend this to a friend
