Fizz Saver Drink Dispenser

The Fizzsaver Drink Dispenser is a simple kitchen tool that can be attached directly onto your 2 liter soda bottle. Keeps drinks carbonated and dispenses just the right amount right from your fridge. Simply twist dispenser onto the top of a plastic 2-liter or 1-liter bottle, then invert the bottle to dispense drinks into your glass. Seems to be creative and simple solution, but it has got negative reviews. [$3.90 Buy]
