well Ive done the pay sites and free ones. The paid sites at least give more local ladies, however, about %90 of the time the pics they sent do NOT at all look like them, which is already a no-go because it shows dishonesty. Also have had several propositions from prostitutes, which is not why i am on a dating site to begin with, not my lifestyle.
No dates were more than one, it was mostly bad that I couldn't wait to get away to be honest. Chemistry is there or it isnt.
The free sites are about 99% scams that want an itunes card or their grandma is dying and need money.
That has been my experience so far. I am not on any at the moment as I have other priorities at the moment keeping me busy.
