We saw her at a live show once in our area. From what we experienced, she was 'spot on' with her channeling.
Many years ago, I saw a medium in Florida (who is now passed). I still have a cassette tape of my hour long session with him. Without going into great detail which would be very long, he was the real deal to me.
Also, my ex husband was there during the reading (who was skeptical), and his younger sister came through which totally surprised him.
My experience is that until you actually have a personal reading with them (he only knew my first name and nothing more), only then can you make the decision.
