The amount of exposed components and the control stick in particular makes the device look pretty unfinished. The stick in particular is pretty unwieldly; it should be a handheld remote. That big metal pole is probably a safety hazard falling off when hitting a bump...<p>A good choice by the designers to use standard Li-Po battery packs, but the cost of the unit without batteries is ridiculously expensive. Okay, good quality materials and manufacturing, but still... And at 33kg not including the ball (another 5kg) or batteries (who knows), that thing is frikkin' heavy!<p>Not saying it isn't a good idea, but I don't particularly like the execution. I'll stick with my electric skateboard.
