I HAVE used one, (but it was for the rescue, so if was free).

I am along the belief that they may have some helpful insight, and it would be VERY entertaining, but I draw the line at believing them word for word.

The psychic I used does it on the phone. A photo sent (or emailed) to her is helpful for her, but no body language can be read as she does not see you.
