The biggest risk of 'hoverboards' exploding comes from their batteries - and the quality of battery fitted to the device.
These batteries work in a similar way to the one on your laptop or smartphone, but are significantly more prone to going wrong.
This is not thought to be down to the scooters, but rather the quality of battery being used in them.
Those looking for a cut-price hoverboard are therefore at risk from low-cost batteries being mass-produced in China.
In hoverboards particularly, those batteries are susceptible to damage when they bump into things at speed.
So how do you tell if your device is susceptible? Buying higher-priced products is an obvious indicator - but the speed at which the hoverboard trend has developed means you might not know until it's too late.
