LOUISVILLE, Ky. (WDRB) -- Officials are warning holiday shoppers about one of the hottest gifts this season.

The National Association of State Fire Marshals says hoverboards can catch fire and explode. One hoverboard explosion even caused a house to burn down.

Officials say to be wary of knockoff brands, which aren't as safe.

The United Kingdom recently seized 15,000 hoverboards after finding that more than 80 percent had faulty plugs that could lead to overheating.

A good board with a proper battery costs anywhere between $500-800.
