A smartwatch designed to help keep wearers fit and healthy is causing more harm than good, according to some users.
A string of Samsung Gear Fit2 wearers have come forward to complain of burn-like marks left on their arms – and some have been left with permanent scars.
They have suggested that this could be caused by the device overheating, while others speculate that an allergic reaction or contact with water might be to blame.
