Four thousand dollars to ride a single-wheeled skateboard, marketed as a hover board, for a total of 16 minutes, seems like a scam. Shouldn't a hover-board, hover? Having said that, with a small marketing and price adjustment (with a large impact), I could see it being a neat form of transportation.
