Want by fridge

Sure, plug it in, put anything that was cold when you bought it inside the fridge. When you want to eat or to cook something, open the door (it will have a handle on it, right on the front of the fridge) and reach in to take out what you want to use, close door again.

You can also use it to make ice! But that's too complex for a forum, need to do a web search and you will find lots of info on how to do that.
