If you have a LayZ Board Hoverboard, Oklahoma Attorney General Mike Hunter says you should stop using it immediately. Officials believe it was a LayZ Board Hoverboard that caused a house fire in Pennsylvania in March that killed two young girls. Hunter says the product should not be purchased or used under any circumstances. If you have one, Hunter says you should take it to a recycling center immediately for safe disposal. The boards were made in China and more than 3,000 units were imported into the United States. (photo provided)
