If your heater prong is loose that's usually a big no no or any prong. That can have a big risk and may cause a spike on your heater and cause it to blow and spark your outlet.
If your going to buy a heater that is made out country always look for reviews on that product online to be on the safe side and (UL) certified. Sometimes cheap can have a risk
