With its features, you can be sure that you take care of yourself while giving your baby the nutrients it needs. Features: 【Double Electric Breast Pump】 We understand that breastfeeding can be a challenging experience, so we have designed this dual electric breast pump for new mothers. Our electric breast pump, which consists of 1 pump unit and 2 150ml marrow milk bottles, can be used as a single or double, more comfortable and efficient for each novice mother to use it. 【2 mode and 9 suction levels】 The electric breast pump has 2 mode (massage prolactin mode/ pumping mode) and each mode has 9 adjustable absorption levels. Simulate the baby's suction rhythm, give silicone flange pressure strokes and provide bionic gentle massage, comfortable breastfeeding and pumping. 【Return Preventive Design】 Gas and liquid separation design prevents the flow flow and prevents the milk from returning to cause secondary pollution. This design allows breast milk to be safe and hygienic, without the risk of contamination or the risk of damage to the pump motor. In addition, the backflowing design function helps to maintain milk supply and prevent discomfort or pain
