I have used MR in Bangalore on three occasions and worked well for me. You will generally see more black service providers. Spend some time vetting the profiles. Usually, the ones with multiple reviews would be genuine.
I managed to punt two African ladies - one of them was a dream service and one Indian lady with whom I had my first anal experience.
Do not hesitate to haggle a bit on the prices if you want. It is a common practice for India.
