The boards, also known as self-balancing scooters, are quickly being nabbed by celebrities. They don't actually levitate, but are more of a cross between a Segway and a skateboard, no doubt inspired by the Back to the Future movies.

Justin Bieber was seen riding on one on his way to a recording studio. Singer Chris Brown has mastered some impressive dance moves on his hoverboard.

They sure look like a lot of fun but hoverboards can be a real pain in the butt – literally.

YouTube is filled with videos of people falling off them and landing painfully on their backsides. Even Bieber crashed when he first got his.

Rapper Bow Wow told INSIDE EDITION he's fallen off his many times when we caught up with him backstage at TV's The Doctors.

"I fell one time on set on CSI. It was just a quick turn, and boom!" he said. 

The Doctors host, Dr. Travis Stork, an emergency room specialist, said people should be very careful.

He claims that there will most likely be a number of injuries, adding: "The one thing I will say is you're also going to see a devastating brain injury."

"I tell you right now - I would never do this without a helmet," he said. "I would treat this like a bicycle, like a skateboard."

IE took a hoverboard for a test drive at Gotham Scooters in Manhattan and brought along elbow pads and a helmet. The company has scooters for sale or to rent.

The board moves while you’re standing up. It takes some getting used to, but once you have the hang of it, it's pretty easy.

Demand for hoverboards is so huge, there's a waiting list for some models - as long as eight weeks on Amazon.com.

But remember - if you decide to jump on the hoverboard craze, be sure to start out on a soft surface.
