Review: Comfortable fit, and made pumping so much better - These flange inserts were a game changer for my pumping experience. The sizing options made it easy to get a much better fit, which improved comfort and efficiency right away. The silicone is soft but sturdy, and they stay in place well during pumping. I noticed less discomfort and better output once I started using them. They’re easy to clean and fit perfectly with my pump. Highly recommend for anyone trying to fine-tune their flange size and make pumping more comfortable
Review: Made pumping easy for me. - As a first time mom, I would like to tell other moms. Nobody tells you that the flanges that every breast pump come with are too big for you. My first week postpartum was hell because I didn’t know what size to use, or that I had to use a different size at all. I went to a lactation consultant who measured me and told me about these inserts. Not only did it help my milk supply, but my sore and bruised nipples thanked me for them. This made pumping comfortable and bearable for me. And I can use them with both my spectra wall pump and my momcozy wearable pump.
