If a viewer tosses a coin, it will vibrate for longer than the specified number of seconds. For example, even after the vibration for one coin has finished, it continues to move for a while. I purchased Lush3 in November of last year, so it was still within the warranty period, so when I contacted support, they asked me to send them a receipt. I sent a receipt image, but I have not received a reply. I would like to exchange toys.
