Kootu gas powered surfboard

I bought the Kootu P1 surfboard and the security key didn’t come out of the controller when I fell off and the board kept going out into the lake, I had to swim back to shore. I had the wristband on and started using the board as described on the website and other videos but all other people who fall off there boards, the board stops or shuts off mine kept going. Any info on this?

Never heard about Kootu P1. Do you have a link?
