Ultrasonic Beer Foamer - Opened, Like New This is a beautiful item. I impulsively bought this handheld beer server to impress at a camping trip. It's a device that uses ultrasonic waves to create fine, creamy foam on beer. I opened it, put in batteries, and tested it, but I've never actually poured beer with it. You set a beer can, and while pressing the button on the neck, you pour the beer. The sound of pouring beer plays from the speaker on top, and the blue LED lights spin while the button is pressed. Pressing the button while pouring creates creamy foam using ultrasonic waves. If you don't press the button, you can pour normally. New batteries are included. Operation has been confirmed. An ultrasonic foamer that easily foams beer. - Product Name: Ultrasonic Beer Foamer - Product Type: Beer Foamer - Compatible Beer Sizes: 250ml, 330ml, 350ml, 500ml - Diameter Range: 54mm〜56mm - Product Specifications: Size: 130mm x 117mm - Operating Temperature: 0℃〜40℃ Thank you for viewing.
