Product review (4 stars): You don't need to buy the AC adaptor
Don't be "tricked" into buying the AC adaptor since it shows you an upsell message saying the two items are purchased together - the item comes with one. Regarding the item itself: Keep in mind this is a novelty item. It's not meant to be a fancy vending machine. There is also a pretty annoying design flaw. The way this thing dispenses is by dropping sodas from the various shelves where the corresponding buttons are. Sodas in the higher shelves have a higher drop and thus get shaken up a bit which isn't fun when opening up the can for consumption.
