Pictured here is the Hisun Efoil controller. There are three buttons used for pairing, on, off and motor speed control. It’s not waterproof and must be used with a dry bag. Dry bag is not provided. There is a magnetic kill switch, the red button pictured on the board, that connects to the user’s leg via a surf leash. When you fall off the board, the red magnetic button disconnects and kills the motor. Otherwise, the board would keep going with rider in the water. It frequently comes disconnected while riding the board and causes unwanted motor shut down.
As for the factory, all of my dealings were with a woman named Lisa. One of the many problems that I experienced with the Hisun was a defective motor that went bad after one month of use. The board came with a one-year warranty. I exchanged numerous emails with Lisa concerning this defective motor. She gave me a royal run around and convinced me that the factory had no intention of replacing the motor and Foil assembly. The vendor in Illinois that sold me the board replaced the motor and foil assembly from their inventory eventually because he was a good guy And was trying to stand by the product. The new motor was a virgin one which had incompatible couplings with the version 2 board that they had also sent me as a replacement for the defective version 1
