Review: Reliable breast flange - These nipple flanges have been such a game changer for my pumping experience. I really appreciated that the set came with multiple sizes, which made it so much easier to find the right fit. I actually needed two different sizes—one for each breast—and having options included made all the difference in comfort and effectiveness. Using the correct flange size noticeably improved my pumping sessions. It helped with better suction, more efficient milk flow, and much less discomfort compared to standard one-size options. The flanges feel well made, smooth, and gentle on the skin, and they fit perfectly with my breast pump without any issues. I also love that this set eliminates the guesswork and extra cost of buying multiple flanges separately. It’s convenient, practical, and especially helpful for breastfeeding moms who are still figuring out what works best for their bodies. Overall, this was a very thoughtful and useful purchase, and I would highly recommend it to any pumping mom who needs comfort, flexibility, and a better fit.
Review: Soft , good fit - I love that it includes multiple sizes (13, 15, 17, 19, and 21mm), which makes it easy to find the perfect fit without having to buy separate inserts. The sizing variety is especially helpful for moms who are still figuring out what works best for them. The silicone is soft, flexible, and very comfortable against the skin. Once inserted into my 24mm flange, it stayed securely in place and created a better seal, which noticeably improved comfort and suction. Pumping felt less painful and more efficient compared to using a standard hard plastic flange. Cleaning is simple, and the inserts seem durable even after multiple washes. This kit is a great value for the price and perfect for moms who want a more customized, comfortable pumping experience. Highly recommend for anyone using 24mm breast pump flanges who wants better comfort and fit!
