Momcozy Hands-Free Breast Pump S12 Pro, Wearable & Portable Pump with Soft DoubleFit Flange, 3 Modes | 9 Levels Double Electric Pump, Smart Display, 24mm, 2 Pack, Cozy White

Momcozy S12 Pro breast pump is designed to ease your breastfeeding journey with its soft silicone cup that fits snugly around your breasts, flexible 3 modes, and 9 pumping levels. Along with a snap-on reminder sound to not only fix well the motor and collector but also prevent milk leakage from the loose milk cup. With an upgraded double-sealed flange design, it can snug tighter and closer to your breasts to pump more efficiently. 1. Ensure the breast pump accessories are installed correctly (* and install the motor on the milk collector (it is correctly fixed if there's a “click” sound), and make sure the flange fits your breast well when pumping. 2. Choose the correct size flange. (Other size like 15/17/19/21/27mm is also available in Momcozy Amazon store) Use the ''nipple measure tool''(included in the box), and select the flange according to the measurement size. (Be sure to measure the diameter of the nipple alone—do not include the areola.) 3. The silicone accessories can be replaced every 3 months or so according to the installation and suction status of the breast pump. Momcozy S12 Pro wearable breast pump is designed to be worn with your standard nursing bra. For a better pumping experience, make sure there is no space between the breast pump and your breast, and it cannot be moved easily. Suggest bra style: full coverage/stretch fabric nursing bra. If your bra isn't flexible enough, you can use a bra adjuster attached to create more room. You can watch the linked videos to help you solve the problem. If you have any questions, please kindly let us know, and we will provide you with the corresponding solutions. Bon shopping!
