PersonalFit Flex Breast Shield for All Medela Pumps | M-24mm | 2Ct

Such a great fit! Very comfort and easy to clean

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!

This breast shield is great! No discomfort or irritation! Just make sure that you select the right size for you.

When I delivered, the hospital provided a package of pump parts with the original shields, and my insurance pump came with the same ones. Although I was sized correctly by a lactation consultant, the original shields just weren’t comfortable. I constantly felt like I couldn’t move and I had to make sure my pumping bra was super tight, otherwise I was losing suction around the edge. It was frustrating and added unnecessary stress to the process. One day, I came across these Medela PersonalFit Flex shields on Amazon, and they’ve been a complete game-changer. They’re significantly more comfortable, stay in place without gaps, and don’t lose suction like the originals. Since then, I’ve switched to Medela’s collection cups, which I highly recommend if you’re looking for an upgraded setup. However, if you’re sticking with the original pump parts, these shields are an absolute must-have. They make the whole pumping experience so much easier and more comfortable!

TL;DR: comfortable, four stars for length of connector which may be too short for some users. I’m comparing these to the maymom single piece Medela replacement flange in a size 21mm which I found to be nearly identical to the Medela flange of the same type. I use these with a Spectra I found these shields to be incredibly comfortable in comparison to the typical shield, the oblong shape is definitely more ergonomic, and I like that you can rotate the position to suit your breast shape. I don’t have very stretchy nipples, so the length of the straight piece was not an issue for me. But I do see where that could be an issue for some women. I don’t think that I got more milk faster, or least not a noticeable amount. But my pumping session was far less miserable. I will note I also used the Bamboobies Pumping Lubricant and if you’re having issues with comfort I highly recommend using a lubricant. These are very easy to clean, the silicone rim could attract some hair but I store all my parts in a wet/dry bag so they don’t sit out exposed to elements in the house or office. I do think the suction is better because the fit it better. I have 38DD bust and use 21mm flanges (small) and they fit me great.

These are my favorite pump shields so far. They aren't just oval, they're also slightly curved so they cup your breast without any pressure points. The tunnel is a little short which might be a problem for people with elastic nipples. I bought the 24 mm and use with a 21 mm Maymom short insert.

These are fantastic. 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!

I love these breast shields. The ones that typically come with the Pump In Style (I guess just the regular PersonalFit) do not work well for me - my whole nipple and areola gets pulled in no matter what size I use, and I end up only being able to get about 2 ounces total from a single session versus about 3-4+ ounces with the PersonalFit Flex shields. They really help with getting a better seal and the shape is just hands-down better for me in terms of fitting my breast shape. One downside is that the silicone around the edge has started to become detached from the harder plastic in the center after only about 6 months of use (fyi, I pump 3-4 times a day, 5 days a week). I leave them on a windowsill to dry so maybe the sun damaged them, but probably you should plan on needing to get a new pair halfway though your breastfeeding journey. Edit after reading other's reviews: Another potential problem with these flanges is that the tunnel is shorter than the regular flanges that come with the Pump In Style, which can result in your nipple reaching the end of the tunnel and touching the connector, which greatly decreases your yield. I was actually able to solve this by getting new connectors. The replacement connectors are slightly longer at the tunnel connection than the ones that are supplied with the Pump In Style, and that was enough that I no longer have this problem. The problem with the tunnel length may not be a problem for everyone, and not everyone with this problem will see it solved by switching connectors, but if you happen to just be lacking that little bit of length, then switching connectors may be a solution.

The Medela PersonalFit Flex Breast Shields (2-Pack, Small 21 mm Flanges) have made a noticeable difference in my pumping routine and are a standout accessory for anyone using a Medela breast pump. These breast shields are thoughtfully designed with Medela’s PersonalFit Flex technology, which really enhances comfort and function compared to traditional rigid flanges. One of the things I appreciate most is the soft, flexible rim—it adapts gently to the breast’s natural shape and movement, helping to reduce the pinching or soreness I’ve experienced with other shields. The 21 mm size in this pack fits me well and helps create a good seal, which I’ve found contributes to more comfortable and effective pumping sessions. For anyone who might hesitate to pump because of discomfort, these feel like a real improvement. The shields are very easy to attach and work seamlessly with most Medela pump models, so setup is quick and hassle-free. Having a 2-pack is especially convenient: I can keep one on my pump and have a spare ready to go, which is great for busy days or when I need to switch between locations. In terms of performance, the PersonalFit Flex shields optimize milk flow without causing irritation, and I often finish pumping feeling much more comfortable than I used to. This personal experience makes me confident in recommending them—not just for comfort, but because they genuinely support a more effective pumping experience. Overall, the Medela PersonalFit Flex Breast Shields in Small 21 mm are a high-quality, reliable accessory that I would recommend to other parents seeking better comfort and a custom-fit solution for their Medela breast pump.

Would work fine for smaller breasts. Short neck so not good for bigger or elastic nipples.

This is a great product that provides a good fit and truly does the job as intended. It is very convenient that there are multiple sizes available to ensure comfort and efficiency. For the best results, these shields are definitely at their best when paired with original Medela pumps, as they integrate seamlessly.

Fits well medela pumps. I have to say that buying proper size of the flange that fits my breast, transformed my pumping journey. Recommend 😊
