FAQs
Q1: How to make sure of efficient pumping?
1. Ensure that the breast pump and accessories installed correctly and that the flange fits the breast when pumping. (Install the breast pump on the milk bowl, if it makes a “click” sound, the installation is successful). And the linker 'ears' align with slots in the milk collector.
2. Suggest bra style: full coverage bra/stretch fabric/with nursing buckle/wireless bra.
3. The silicone accessories can be replaced every 3 months or so according to the installation and suction status of the breast pump.
4. Select the correct size flange. (17/19/21/27mm also available in Momcozy Amazon store).
Q2: Will the size of the breast affect the use? How can I confirm the correct flange size?
It does not affect the use, just select the correct flange size.
Measurement Method: Use the ''nipple measure tool''(included in the package), select the flange according to the measurement size or refer to the link ''size selection'' video.

These are my favorite wearable breast pumps. I ve tried quite a few, even the Eufy S1 pro. Well, they are a bit bulky, I find them to get the best output. I love the range in suction and they are easy to clean. I also find them to be on the more affordable side.
