I think they are pretty good at making electric skateboards. Youtube star Casey Neistat is always seen riding a boosted board. He has test driven a lot of electric boards and has told that nothing else comes close to the boosted board multiple times[1][2]. To be honest Casey Neistat appear to be a type of guy who tells what he belives in even if it means loosing subscribers. He gets a lot of hate sometimes because of that.
