I have very mixed feelings of them. I played with them as a teen. Had some pretty cool experiences with them at times. We had used white candles with our sessions and we still had some creepy things happen still. The last time when I was 19 (with my husband) it said we were evil. THAT was enough for me! Especially since having children, Ive never played with one nor plan to. Just the very idea of it being around my youngest (fear of its possibilities to tap into her energy)is enough keep the temptation of wanting to show my oldest what they can do.
