Enhanced Comfort and Efficiency: A Five-Star Silicone Flange Insert!
I am absolutely thrilled with this silicone flange insert that I purchased to use with my Medela Harmony manual breast pump. It has made my pumping experience significantly more comfortable and efficient. While it may pose some challenges when removing or inserting when dry, and cleaning can be a bit tricky, these minor inconveniences are overshadowed by the overall greatness of this product. Here’s why it deserves a solid 5-star rating:1. Perfect Fit and Enhanced Comfort: The silicone flange insert seamlessly fits into the factory flange of my Medela Harmony manual breast pump. This perfect fit provides a snug and comfortable seal during pumping sessions. It creates a cushioning effect and reduces discomfort, allowing for a more enjoyable and pain-free experience.2. Improved Pumping Efficiency: This flange insert has significantly enhanced the efficiency of my pumping sessions. It helps to maximize suction and milk extraction, resulting in increased milk yield. The snug fit and optimal seal ensure that every drop of precious milk is collected, minimizing waste and saving time.3. Minor Challenge with Removal and Insertion: It’s worth mentioning that removing or inserting the flange insert when dry can be a little challenging. However, with a little practice and the use of water or a lubricant, this challenge can be overcome. Once you find the right technique, the benefits of improved comfort and efficiency make it well worth the effort.4. High-Quality Silicone Material: The flange insert is made of high-quality silicone, which is safe, durable, and easy to clean. The material is gentle against the skin and ensures a hygienic pumping experience. While washing can be a bit challenging due to the insert’s design, it is a minor inconvenience compared to the overall benefits it provides.In summary, this silicone flange insert is a game-changer for Medela Harmony manual breast pump users. Its perfect fit, enhanced comfort, and improved pumping efficiency make it an exceptional accessory. While it may require a little practice and patience when removing or inserting when dry, and cleaning can be a bit challenging, the overall benefits and performance of this flange insert are truly impressive. I highly recommend it to all breastfeeding mothers seeking a more comfortable and efficient pumping experience.

Works Well
These were perfect!

Pops Out Often
This helped to make the flanges fit bit they pop out every time I use them. I have to constantly push them back in to be snug enough. They are not the same texture of silicone as the 17mm made by Maymom (those were a softer silicone whereas the 19mm are a bit stiffer but not uncomfortable). I wonder if that has something to do with it.

Size 15 flanges work well with elvie pump
These work well with my elvie double pumps and also fits in my manual pump from the hospital. They are silicone, flexible, and comfy.

Giving 3 stars out of 5 because it doesn’t work with my Medela Freestyle Hands-free pump as indicated. Though it fits the size perfectly it reduces the suction to a minimum so the milk doesn’t flow at all. However, I tried it with my older version Philips Avent electric pump and even though it doesn’t fit ideally, it stays there while pumping. At least not a complete waste of money and I found a use for it.
