She's spoke to me, as well as another family member, regarding our deceased loved ones. Both times, her descriptions were on-point enough that other relatives agreed that she has to be genuine.
I was literally shook, and still haven't mentally recovered, because I wasn't anticipating that she'd bring up a family member at all, and that family member in particular, who was and remains, dear to me.
If you're on the fence, do it, just be prepared, that she may actually speak to your loved ones.
