The GoPrep Formula Feed Maker is an innovative solution for preparing infant formula on the go. It consists of two bottles: One stores boiling water, while the other cools the food to the ideal temperature in just two minutes. An easy-to-read digital display shows whether the milk is too hot. As soon as the star on the lid turns blue, the food is ready for consumption. The appliance complies with NHS guidelines, which stipulate that infant formula must be prepared with boiling water to kill bacteria. After boiling, the system quickly cools the food to the perfect temperature. Cleaning the appliance is simple. The bottle is washed in warm soapy water and then sterilised with 240 ml of boiling water. After capping, the bottle is shaken for 10 seconds, then left upright for two minutes and turned upside down for a further two minutes.
