My Mom and my aunt - though both Jw's at the time - let curiousity get the best of them. They bought one and played it from time to time. Every time they did, mu mom was a wreck for a few days. She said once they asked it to spell God's name. She said it spelled all sorts of things - even SATAN. They kept pressing and it eventually started to spell JEHOV.... then the pointer through itself off the table. They got so freightened that they got a hammer and broke the thing to pieces. The next day they glued it back together and it still worked.
They left it at my aunts house for a long time. They put it up in the cupboard in the kitchen and for months my aunts family had many unexplained things going on in the house. The one that I recall was the time my cousin [at 4 years old] got out of bed to get a drink and go to the bathroom. He said [and as far as I know still swears to this day] that he got a cup, and when he placed it under the faucet the water came on by itself and shut itself off. Then at the john, after he peed, the stool flushed itself. He ran terrified into his parents room and related the entire matter to them.
By this point everyone was terrified of the board. Mom took it out back and tried to burn it. It would not burn and so she threw it in the trashcan.
I never touched one myself. But I think there is something that does not meet the eye.
