Zomee's design works with new mothers to make expressing breast milk as comfortable and easy as possible. This electronic breast pump uses up to date technology that makes operating it effortless. With anti-backflow system, milk will not flow backward or back up other parts of the pump, which can create mold and bacteria, so you can count on pumping the cleanest and freshest milk for your little one. Busy moms will appreciate how quick and easy it is to use.
