Hi there Esprit,
I don't have any guidance for you as yet but I just ordered these on the advice of a friend (I know, I know, I am a little skeptical also) and will let you know how I go.
There IS a guarantee after all so that gives us SOME security.
I SOOOO need something to help shift my energy and I wanted to have a less FULL ON experience of the Holosync technology so thought this was a good option for me. Will keep you posted.....
Blessings
