I would love to order but Im afraid if people didn't receive it after 3 years my money may not come back if I pre order
IMHO, you should wait until it appears on Amazon or HoS, because if something goes wrong, it becomes Amazon or HoS's problem and not yours. If you pre-order, you are at the mercy of SquareOff themselves.
Personally, I would probably go for other options if you want something now. The novelty of a self-moving chess board wears off pretty quickly.
