The microwave is a food - cooking device that is, undoubtedly, very expensive. Unfortunately, the cheaper models are known for their hazardous characteristics. They tend to make food somewhat poisonous or even radioactive. Scientists say that it's not enough to make you feel ill but it won't make you healthier. Some microwaves get overheated very easily. This is why you should always operate with maximum attentiveness because you might accidentally burn your hand when taking your food out.
