Agree with AndrewP, though Bumble was a bit worse in my case.
If you only test one thing on that one, make it how quickly you can narrow a list down.
Gave the site a fair run over 5 weeks and kept coming back to how quickly it starts asking for money.
Unless you're in a major metro, expect how quickly you can narrow a list down to be the limiting factor on the service.
Has anyone got Bumble working properly outside a major city?
Someone in another thread pointed me at what Datewander does with filters and it was a fair shout.
