Lol. It's just another one of many divination tools. Tarot, Crystal Ball, Runes etc. It does all depend on the user and what they are doing with it.

Parker Brothers came out with it in the 1970's and placed this spooky stigma on it to sell more. If you don't know what it's really for and use it as they advertise then yeah, you might get something you don't want.

If you go into it with negative energy, you are going to get negative back. Same with positive.

It's all you get what you give. It does help to play nice with this little diddy.
