I received my 2WD board last week. The board itself is great, but my controller has proved completely faulty. At first, the low battery indicator for the remote would show up after 5 minutes of using it. After restarting the controller, it was back to full battery, so clearly something was off with the low-voltage protection circuit.
The second day I had the board, I was riding about 30mph toward an intersection and started braking. The brakes would not work, and I looked down to see my controller was completely shut off. Fortunately, I had a green light so it turned out okay, but I could have been killed in that moment due to poor quality assurance from OwnBoard. I refuse to ride this board until I get a new controller than I can trust. I reached out to their support team and so far, it seems like they don't believe that this is an issue. They have not offered to replace the faulty controller or any other kind of solution. If you value your life, I strongly recommend looking elsewhere for a eboard. This is absolutely unacceptable for a $2200 skateboard.
