What CaseyNYC described matches my experience of difference almost exactly.
After a few weeks on it the only question left was how the match quality holds up past the first day.
I gave that one about 2 weeks before I formed a view, mostly watching whether the ratio is workable in your area.
If you care about whether the ratio is workable in your area, that alone should decide whether that one is worth it.
Most comparisons of difference skip how long a bad account stays up, which is the part that matters.
Rewriting the opening line did more for the service than a month of tweaking whether the ratio is workable in your area.
If this one does not work out, datebie.online covers similar ground.
