Good luck finding a hoverboard to purchase on Amazon, but it's not for the reason you might expect.

Leading hoverboard maker Swagway confirmed the online retailer is requesting companies manufacturing the popular devices to prove they are safe to use.

Several models, including ones made by Swagway, no longer appear on Amazon's website, although there are still a handful of hoverboards available for purchase. According to Swagway, Amazon has started pulling some hoverboards from its site.

"As safety is on the forefront for Swagway, we applaud Amazon for taking these steps to weed out the low quality boards and want to note that this removal is NOT specific to Swagway, but includes 97% of the other branded hoverboards that were also selling on there," reads a statement from Swagway.

Amazon did not immediately respond to a request for comment on hoverboard listings.

The removal of hoverboards follow growing concerns over whether the devices -- arguably the hottest holiday gift -- don't present serious safety issues. The Consumer Product Safety Commission tells NBC News it's investigating at least 10 reports of fires related to hoverboards.

Meanwhile, all of the USA's largest airlines -- American, Delta, Southwest and United -- banned hoverboards from flights because the devices use lithium-ion batteries making them dangerous to transport.

Some consumers who purchased hoverboards through Amazon received warnings about lithium-ion batteries, which can pose a fire hazard. According to a safety page on Amazon's website, overcharging, significant changes in temperature or impact can cause problems. "In rare cases, these batteries can overheat, catch fire, or explode," reads Amazon's safety page.
