Pro Lessens the things you need to bring along
The Mixie has a built-in compartment at the bottom. It keeps the formula separate from the water until you pop the button on the bottle to mix them. This design minimizes the need to pack a formula container, water, and bottles separately. It also eliminates the need to use a cooler to pack pre-mixed formula.
Con Requires thorough cleaning
The Mixie has more pieces than the standard baby bottle and it takes more time to clean. Although a dishwasher does a fine job of quickly cleaning it, those who choose to hand wash the bottle have to spend extra time and effort brushing the small parts to make sure no left-over milk is stuck in the nooks and crannies.
