Ive tried alot of dating sites, the free ones are the worst due to most of the people you run into / profiles are fake, and scams. Zoosk is nice since you get matched with certain people but also can browse profiles unlike some dating sites. I never liked the coin thing, but atleast you can earn coins daily and not always buy them, on top of paying for a membership.
In the end its a good dating site, One of the dating sites I would recommend, if you want to be serious about what your looking, Zoosk is pretty good,
