The portable soda dispenser/fizz saver keeps your soda fizzy and turns the bottle into a keg-like dispenser. You twist the dispenser on to the top of a plastic 2 liter bottle then flip the bottle upside down to dispense drinks. The soda will stay carbonated and you can pour it right from your fridge. Keep soda and other carbonated beverages from going flat with the ingenious fizz saver dispenser, which serves drinks directly from your refrigerator. Serve fizzy drinks right into you glass via the convenient, push-in dispenser. This is a sealed device, so it is better to use carbonated beverage, especially for sodas, for gas is necessary for it to work. If the beverage you fill in the dispenser lacks gas, it doesn’t work well. Only when you press the bottle, beverage will run out from it Note:If leakage is found, please adjust the white rubber plug. Great for use at home, office & camping, at parties etc.
