By John J. A Whole Lot of Fun – but requires caution!Review for SWAGBOARD VIBE Bluetooth Hoverboard, T580So far so good. The battery time seems to last a couple of hours, thought it would be more. It charges quickly, light turns green when charged. Surprising that it’s recommended not to overcharge – why not incorporate a shutoff switch into the charger? Anyway, the girls love it and so far it hasn’t made it out of the house.Posted by John J.
