First in the world hands-free Otherside communication device! You need only the board, spirit or ghost don't need to move the ouija anymore. Symbols will light up from the inside so you will be able to read your messages and spirit or ghost just need to turn on a red bottom entry LED. Two MEMS microphones allow your interlocutor to clearly hear your questions. WiFi connectivity gives you an opportunity to "dial" without a Medium anytime anywhere. And it has Bluetooth as well, because: "Everything is better with Bluetooth"! This board is powered by a single 10440(AAA) LiFePO4 battery that gives you up to 2 hours of seance.
