The box is damaged, but the contents are brand new and unopened. 【Double pump reduces pumping time by about half*1】Compared to a single pump (alternating pumping from one breast), a double pump (simultaneous pumping from both breasts) significantly reduces pumping time, allowing for more efficient use of time. Research has also shown that the amount of breast milk that can be pumped increases by 18%, and the fat content of the pumped breast milk also increases. *1 Compared to our single pump. 【With the Flex breast shield, get more milk, more comfortably*2】The "PersonalFit Flex breast shield" included with this product is designed with an opening angle of 105°. This reduces pressure on the breast, and research has shown that up to 11.8% more breast milk can be pumped compared to using our conventional product (PersonalFit breast shield, 90°)*3. *2 Compared to the conventional breast shield (PersonalFit breast shield, 90°) *3 Sakalidis VS et al. Breast shield design impacts milk removal dynamics during pumping: A randomised controlled non-inferiority trial. Acta Obstet Gynecol Scand. 2020:doi: 10.1111/aogs.13897. 【Easy button operation for natural and gentle pumping】When a baby nurses, they first stimulate the flow of breast milk with a fast rhythm, and then drink the milk with a slow, deep rhythm. The new Swing Maxi electric breast pump is equipped with its own "2-Phase Expression Technology" that reproduces this natural way of a baby's nursing. With intuitive and simple button operation, this natural way of a baby's nursing can be reproduced, allowing for gentle and efficient pumping. Furthermore, the suction pressure can be selected from 9 levels to match your physical condition on that day. 【Pump anywhere】Because a rechargeable battery is built-in, you can pump not only in front of an outlet, but also carry it to your favorite place. A USB power adapter and cable are included, and USB charging is possible. It operates for 1.5 hours on a full charge (about 6 times for simultaneous pumping from both breasts). Also, the main motor can be carried around by hooking your finger on the included loop.
