The product is not warm enough.


Since heat generation of HEAT CHARGER® is affected by 1) high or low ambient temperature, 2) thermal properties of the clothes being put on, 3) individual differences in age and physical condition of the user, 4) amount of incorporating air, and other factors, uniform temperature is not always provided. If warmth is not sufficient to use with the Heat Cushion, Remove HEAT CHARGER®s temporarily from the pockets of Heat Cushion to ventilate, and shake gently several times. When HEAT CHARGER®s become warm, place one HEAT CHARGER® in each pocket on the back of cushion. When no longer warm, Dispose of HEAT CHARGER®.
