Great Scott! Over 15,000 hoverboards seized in UK

The U.K. is confiscating hoverboards

More than 15,000 "hoverboards" have been confiscated at U.K. ports and airports in recent months, after being regarded as "unsafe" for personal use.

Officers from the U.K.'s Trading Standards have inspected over 17,000 self-balancing scooters since October 15, and seized 88 percent of these self-balancing scooters, over fears they could explode or catch fire.

The self-balancing scooter has fast become the "must have" gift for Christmas 2015, with the ports and borders teams revealing they'd seen a "significant spike" in the number of these vehicles in recent weeks, as the holidays approach.

However, concerns have been raised over safety issues with the product's design including concerns over plugs, batteries, chargers and cabling. Many of the items apprehended and tested were found to have plugs without fuses, which the organisation said increases the danger of hoverboards from overheating, catching fire or even exploding.

"We suspect that most of these products are being imported for onward sale domestically as Christmas approaches – we urge consumers to be on their guard when purchasing these products," Lord Toby Harris, Chair of National Trading Standards said in a statement.

Criminals and some manufacturers could use the high demand surrounding the Christmas holidays to "exploit" and "flood the market with cheap and dangerous products," Leon Livermore, chief executive of Chartered Trading Standards Institute (CTSI) added.

This news comes shortly after the U.K's Crown Prosecution Service confirmed in October that it was illegal to drive self-balancing scooters – including Segways and hoverboards – in public in England and Wales. The vehicles were considered too dangerous to ride on pavements and roads, therefore were only permitted on private property.

For anyone thinking of purchasing a hoverboard, the organisation suggests online deals should be vigilantly checked to see if the product comes from a genuine seller, while reading the terms and conditions.

In recent months, many reports and videos across the globe have shown hoverboards catching alight, therefore the organisation suggests that even when owning one, to check the device and not to leave it charging on its own or overnight.

With the Christmas holiday season approaching and deals from "Black Friday" and "Cyber Monday" still settling, Trading Standards suggests not to immediately go for a bargain, adding that if it appears "too good to be true", it probably is.
