Yanno if they're going to try and sell that thing they probably shouldn't have the person demoing it looking like it's a pain in the ass to keep your balance.
Looks like it may be real, buuuuut...
They are way way way exaggerating and hiding information about it.
The "Slightly larger than a skateboard" part is hilariously bad. It's so large and cumbersome, you couldn't even "Skate" on the ground with it, making it unusable. Not to mention, they cut all the sound out of the video, and I'm sure that thing is loud as hell, I would guess it makes more noise than a lawnmower would.
