At the UL headquarters in Northbrook, Illinois, we got to see all sorts of hoverboard safety tests.
One existing problem area has to do with the lithium ion battery packs.
A problem with one cell can lead to serious problems with the product, including fire.
But, UL has announced procedures to test hoverboards for safety.
One test involves piercing a nail through a lithium ion cell to see how it reacts. Spoiler alert: This one burst into flames shortly after this photo was taken.
They also stick hoverboard wheels into a vice over a 7-hour period. If it overheats, it's disqualified from certification.
Counterfeiting is another problem, where you might see a "UL logo" on a box, but it doesn't reflect a true, UL-approved certification.
You might also see potential counterfeiting on individual components.
UL has a team that focuses on counteracting this, though, and plans to introduce hologrammed stickers that are much more difficult to replicate.
