This machine holds five rows of two cans each. Just push the button to the right side and the drink is dispensed below -- just like a real machine but no need for coins. To fill, just open the door with the pull handle on left and place drinks inside. My main concern was whether it would keep drinks cold but they are icy cold. Machine runs quietly so you'll hardly notice it's on. No assembly required. Just open the box and plug in. Fun to have in the home or out by a pool. It also comes with a cigarette lighter adapter so you can take it with you on a tailgate party or beach outing and run it from your car. I haven't done that yet, so not sure if it makes a difference in how cold it keeps the drinks.But no matter how you use it, it's sure to be a conversation starter and be practical at the same time.
