Ultrasonic Beer Server

When it comes to beer, there are two things that matter the most, perhaps even more than the taste: it needs to be cold and it needs to have a thick, creamy head. Anyone who loves beer will agree that if you have these two, it works fine even if it isn't your favorite type or brand, especially on a summer day when you want something to cool you down. The Ultrasonic Beer Server makes sure you have both and also works as a hot or cold drink bottle for when you aren't in the mood for beer! The Ultrasonic Beer Server is three devices in one: depending on which cap you use, it becomes either an ultrasonic generator producing 40,000 vibrations per second that create an amazingly thick foam, a holder for your canned beer, or a tumbler from which you can drink your beer. And it also comes with a regular cap that turns it into a vacuum-insulated Thermos-style bottle that keeps your drinks hot or cold for at least six hours! Get it in white, black, or beige and enjoy your beer the way it was meant to be enjoyed!
