When using a microwave to cook, we usually follow the manual to set time. Since the proper time is different according to the condition of food, sometimes the food is still cold or too hot after taking food out from a microwave. This product change colors to yellow, green and red and help users to check food temperature. So users don't need to set time two or three times and cannot burn their hands or mouth.
