Review: The short stem didn’t bother me - I’m brand new to pumping. I’m a first time mom and up until now i only ever breast fed my baby. My sister gave me her old Medea breast pump and so I’ve been using all the flanges that she had but realized that I needed to get something different. It has been so painful to pump. My nipples have been so sore and while pumping i feel like the edges of the cone pinch my skin between it and the pumping bra I use. I was limping along until I found that my Falange was too big and sucks my areola in. I guess your supposed to compare your nipple size to change. If you stimulate your nipple to pop up and it’s a little smaller then a dime then you need a 21mm. I saw these ones that have rubber along the edge and So far the pain that I was having is sooooo much better. A lot of reviews talked about how the short stem was bad for them. I’m not sure why that it. I almost wonder if they are using too big of a flange?? If your nipple is sucking so far in that it’s blocking the milk from coming out I think it’s too big. Mine were sucking in pretty far when I used the big ones. But now even when my nipples are lubricated they still don’t suck in that far. But maybe it’s a difference in anatomy? Anyway I’ll say this things I like about this product. 1 more comfortable. Doesn’t pinch my skin or hurt my nipple. 2 the shorter stem seems to get the milk into the bottle more efficiently. My milk sprays all over and would coat the inside of the flange and I could never get those drops to go into the bottle. Now there is not an inch of empty space stealing milk. And when you don’t produce a lot like me every drop counts! 3 the oval shape contours to my breast better. 4 the rubber ring doesn’t hurt so bad to be peeled off. The only thing I don’t like but is no fault of the product is that my right breast seems to leak milk onto my shirt. I think this is because of the shape of my nipple? Anyway I thought it was great the shorter stem doesn’t bother me and I needed to have a smaller size. I would recommend! Review: EP Game changer - As an exclusive pumper, I am chained to my breast pump. I pump 8 times per day on average with my medela electric breast pump. The flanges that come with the pump left raw, hickey-like marks on my boobs. They also caused a lot of leakage and us mamas know that breast milk is like liquid gold; every drop counts. These solved all my problems. These have a perfect fit. The gripped outer rim is strong enough to keep the pump parts in place, but not too rough that it hurts when wearing. These work great with my hands free nursing bra attachment as well. I also noticed that I have to pump for less time to get the same amount I was getting with the normal flanges. These were a lifesaver for me and I will absolutely recommend to any mama that pumps, whether that be once a day or 8 times a day. ## Features - COMPATIBLE WITH MEDELA BREAST PUMPS: all variations of Pump In Style, Freestyle Hands-free, Swing Maxi Hands-free, Freestyle Hands-free Mini - NOW WITH INNOVATIVE MEDELA FLEX TECHNOLOGY THAT ADAPTS TO YOU: Engineered with advanced Flex technology, our PersonalFit Flex breast shields allow you to pump comfortably in a variety of positions, while a 105-degree opening angle helps reduce pressure - REMOVES 11.8% MORE MILK PER MINUTE: Medela PersonalFit Flex breast shields remove significantly more milk and help moms pump more milk than pumping with traditional breast shields – so you can maximize your pumping efficiency and optimize milk output - CONVENIENT RANGE OF SIZES TO CHOOSE FROM: With 4 size options, mom can find the most comfortably fitted breast shield for her unique body while avoiding discomfort - MADE WITHOUT BPA: Like all other Medela breast pump parts and accessories that come into contact with breast milk, our PersonalFit Flex breast shields are – and have always been – made without BPA and are instead made with food-grade plastic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L197S97 | | Additional Features | Soft, Natural Feeling | | Best Sellers Rank | #2,823 in Baby ( See Top 100 in Baby ) #32 in Breast Shells & Nipple Therapy Products | | Brand | Medela | | Brand Name | Medela | | Capacity | 680.39 g | | Color | Clear | | Customer Reviews | 4.6 out of 5 stars 20,146 Reviews | | Global Trade Identification Number | 00020451366531 | | Included Components | 2 Breastshields | | Item Weight | 60 g | | Manufacturer | Medela, Inc. | | Manufacturer Part Number | 101036653 | | Material | Polypropylene, Thermoplastic elastomers | | Material Type | Polypropylene, Thermoplastic elastomers | | Material Type Free | BPA Free | | Model Name | PersonalFit Flex | | Model Number | 101036653 | | Number of Items | 2 | | Power Source | Manual | | Size | Small (Pack of 2) | | Special Feature | Soft, Natural Feeling | | UPC | 020451366531 | | Unit Count | 1 Count | ## Product Details - **Brand:** Medela - **Included Components:** 2 Breastshields - **Material:** Polypropylene, Thermoplastic elastomers - **Power Source:** Manual - **Special Feature:** Soft, Natural Feeling ## Images ![Medela PersonalFit Flex Breast Shield for Most Medela Pumps, S-21mm, 2Ct - Image 1](https://m.media-amazon.com/images/I/51E28oczgdL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can these be used with spectra pumps?** A: We have only tested them for use with our Medela breast pumps.

Have a lovely day! **Q: Does it fit the madela lactina hospital grade breast pump?** A: I Google searched that model, and as long as it was truthful then yes it should. It's just the breast shield part that connects to the part that screws onto bottle and the tube connects to. It's very comfortable compared to the normal hard plastic type. Make sure you order the correct size to fit you, it does make a difference **Q: Could this be compatible with the Lansinoh Smart double pump?** A: Hello Amazon Customer--- Our products are only tested with our Medela Breast Pumps so we are not able to say if these would work for the Lansinoh Breast Pump. Please reach out to Lansinoh to verify which products are compatible with their pumps. Have a great day! ## Customer Reviews ### ⭐⭐⭐⭐⭐ The short stem didn’t bother me *by A***R on March 21, 2020* I’m brand new to pumping.

I have the medela pump in style and have been using it for a couple months with the 24mm shields that came with it. I had never really looked into the details or importance of breast shield sizes until I started shopping around for ones that would be more comfortable. I read mixed reviews on these shields, with many users complaining that the tunnel part was too short and that their nipples reached the end of it, making the shields uncomfortable and unusable for them. I had to google about how to choose the right size, but was very surprised to learn that the size of shield you need is related to your nipple size, NOT cup size. As a large breasted woman, I assumed I would need a large size in these, but turns out I need a small--I never would have guessed that on my own. I wish sizing was explained in the item description here, but I now realize the reviews about the short tunnel troubles were completely related to the user having the wrong size. With the correct size, pumping is easier, far more comfortable, AND I am absolutely getting more milk. Don't guess your size- look up how to measure your nipple to choose the correct one and these will change your life! ## Frequently Bought Together - Medela Medela Breast Shields - PersonalFit Flex, 21mm Medela Breast Shield Shaped Around You for Comfortable and Efficient Pumping, Made Without BPA, Pack of 2 Breastshields, Clear, 21mm - Medela PersonalFit Flex Replacement Connectors, 2 per Count, Compatible with Pump in Style MaxFlow, Swing Maxi and Freestyle Breast Pumps, Authentic Spare Parts - Medela Breast Milk Collection and Storage Bottles, BPA Free, 6 Pack, 5 Ounces, Compatible with Medela Breast Pumps --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/93436987-medela-personalfit-flex-breast-shield-for-most-medela-pumps-s](https://www.desertcart.jp/products/93436987-medela-personalfit-flex-breast-shield-for-most-medela-pumps-s) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-20*
