I never have, but I had always thought they were ugly, drug-ridden, diseased girls charging 20 bucks for a quick BJ. No GFE, either all covered including the BJ or all bare if they're in a hard spot and you got an extra couple bucks to entice them. Basically, I had thought they were really only good for getting a nut, not for anything approaching a normal escort date.

Some girls on there fit what I had thought to a T, but then others are just normal escort-looks, and a few are legitimately beautiful and could be on Eros or Tryst charging 500-1000 an hour. No idea why they'd be walking the street instead. They could even just go dance at a strip club.
Still no idea how the service is, but the looks have been better than expected. Of course this still doesn't take into account the dangers of going for SWer's, like getting into a cop sting or getting into issues with pimp/BF or getting robbed by the girl.
