I really feel you on this, choosing the right master for something so important is not easy and the mixed reviews online make it even harder to decide. My friend actually went to one recently and she said the experience was really personal and meaningful, the master took time to explain the reasoning behind the name choices which made her feel more confident about it. If you can, try asking around in your own family or close friends circle because word of mouth referrals tend to be more reliable than random Google reviews lah. Hope you find someone you can trust for this.
