Why would you choose to use one as part of the Kickstarter Collector's Edition? These are not toys and should never be used to contact spirits.
I'm hesitant to get the collectors edition because I'll only have to destroy the Oujia board rather then risk it ever being used. They don't bring the crazyness that is shown in movies, but they can bring in evil spirits that will cause sickness and torment. There are plenty of documented cases, including my own experiences.
It is one thing to play fantasy, but this crosses the line in fantasy.
