Does your kid collect Hoverboards like you used to collect baseball cards? Then you need the Hoverboard Kart Seat Attachment!You will definately be impressed by how little your kid uses this new toy once the first day's use is over. But, you Have to order it to avoid the meltdown - cause little Timmy has a friend who has one, and by golly they are just soooo coooool!!Yes they work, yes it's a gimmick - standing on the hoverboard is the more practical and funner way to experience the ride.Quality is there for limited use that they get. We did have one several years ago that split the square tubing up by the front wheel.
