Some people love them and hate them – microwaves are not for everyone. There are many reasons why a microwave might be a good idea for you, though. They can perform lots of functions in the kitchen and generally, they are quite reasonably priced, making it perfectly possible to get a microwave for a price that will suit you.
A microwave oven is used to heat up food in the kitchen. They may also have other functions, like grilling. They can be used in a very low setting to defrost food without beginning to cook it. Whilst this is useful, there are very few things that you can do with a microwave that cannot be done in another way with a different appliance.
Microwaves do tend to make it easier though. Heating some soup or cooking some beans will take only minutes. And when you want to eat something quickly, a microwave meal is about as quick as it gets.
