The US Consumer Product Safety Commission (CPSC) warns of the dangers of playing with spinners and the need to take precautions.
In particular, one of the dangers of CPSC is that plastic and metal spinners can break up into small pieces. Therefore, experts recommend not to give a toy to young children and to keep an eye on older children so that they do not put the spinners in their mouths.
In addition, experts remind that spinners working on batteries can explode during recharging, so the agency recommends using only the original wire that comes with the device.
