I've had a few cashouts and after being approved for their fast cashout program - cashouts were received within 4 hrs. I also had many times where I could have cashed out but didn't; I can't blame the casino for that =)))

And so to simply answer your question - yes, I have.

And to add - GoWild is my favourite site to play and I believe once you crack the "curse" as I used to call it before my first win there, you will love it too.
