This looks like fun, maybe a way of fun transport to get back to your car after a DWer 
I love my Electric Skateboard its the best thing I have purchased but I would love to give one of those hoverboards a roll
They had these everywhere in the US last time we were there i think they were selling for about $1500.
Looks cool, but slow - I reckon that speed limit would get frustrating, and you couldn't ride it when the batteries died.
The one in that article http://ridemarbel.com/ looks a better proposition. Gets up to speeds that could kill you and even if you the batteries dies (and you don't) you can still kick push it when dead.
Yes $1500 US, i didn't ride it as im trying my best to stay away from things that will add to my injury list!!
