I can't talk against Ferrari because back in the days they sent me some amazing SP, Kim, Marie (best BJJJ ever blue eyes black hair breath taking beauty), Katrina (small spinner with amazing body) and the list goes on, Yes they did send me bad SP too but I had a lot more positive encounters then negative ones. But back then the price did vary I think at first it was like 180$, then it change to 200$ and 220$, but the last time I book with then it was 240$ tried to cancel but the women said the SP is already on her way to you. That was the last time I paid that much for an SP. Wildtimes sent me some amazing SP too, Christina, a French girls BBW but man was she HOT, Kelly was her name, she had come back from vacation tanned from head to toe and her face and eyes. MTLGFE also had amazing providers but I think I book 1 or 2 times with them.
But I do mind paying that much money for 1h of sex I don't have the means to to do, and at 280-300$ if I end up with a bad service I would be like yeah okay.
Guess that now this hobby will be for people who have tones of money and the little fish like me would be better off trying to find another girlfriend.
