A multi cooker is the jack of all trades of the cooking world. If you cannot decide between getting quality rice cooker, a pressure cover, or a slow cooker, you can have them all with simply buying a high quality multi cooker for your kitchen. You can usually do a number of things with a multi cooker. Many different brands and makes provide you with a number of different features and cooking styles. Generally you will get the choice of being able to do things like using the multi cooker as a steamer, cook, fry, bake, stew, and even make pasta. In some high quality multi cookers like the Vitaclay organic multi cooker, you will also have the option of making things like yogurt or bread as well.
The whole concept of a multi cooker is that it is supposed to make your life easier. It makes cooking easy as all you really need to do is add the ingredients to the cooker and then put up the correct setting and leave it there until done. Usually you will not have to do anything else until the cooker is done and then you just need to plate the food. So to make sure your work is not complicated you should get specific features on a multi cooker that will make sure your most common style of cooking is covered. So if you prefer to bake and fry foods the most then you should get a multi cooker that provides you with the option of doing that.
Other than that you should look at a few safety features that will make sure your cooking experience is not ruined if something happens to the cooker. You should try to get a cooker that has a safety fuse in it and a retractable wire too.
