Adults and children around the world suffered hoverboard-related injuries over the weekend. Many posted pictures of the damage on social media. Twitter user David Douglas posted a pho to of both him and a young girl with the broken arms they suffered on Christmas Day. And another user Erin Rafferty uploaded a video of her mother falling off a hoverboard, with the  caption, “Who let mom on the hoverboard?”

Falling is not the only risk with some hoverboards. They are also a fire risk. At one store in Texas, an employee tried to fix a hoverboard a customer brought in. The hoverboard then caught fire.

Studies suggest that some hoverboard brands have defective batteries o r plugs.

Many major airlines worldwide have banned hoverboards because of the fire risk. But some passengers did not hear the news. Australian actor Russell Crowesaid on Monday about his disappointment that Virgin Australia Airlines did not permit his children to take their hoverboards on the plane.

Major retailers (零售商）are also taking steps to improve the safety of the hoverboards they sell.

It has also advised customers who bought unsafe brands of hoverboards to throw them away.
