This site does not do wonders, if you are in a bad spot on the dating market, this site won't improve it, but more likely point out that you are in a bad spot.
On this kind of sites there are always scammers. I saw them usually being removed within 24 hours.
The site is basically free which gives enough options to communicate with people. Be aware nothing is really free so to use the best features you need to pay. That cannot be a surprise.
The match questions can be very usefull or very silly or too complicated to answer with a multiple choice action. Don't answer queries you do not want to answer, there are thousands so just skip these.
Also many questions are USA-based. The company is USA-based, so the obvious questions about Trump, gun control, mansplaining, micro-cheating are popping up like popcorn.
However the questions have been set up very broadly. If you are a devout christian, you can answer that you want to keep chaste till the wedding, intelligent design is science and are against abortion.
If you are a heteroflexible polyamorous atheist, who loves annilungus, who thinks capitalism is bad and trees have souls you also might find your match.
