  • Great
Exactly what I needed. Great product.
Reviewed in the United States on November 3, 2025 by Amanda

  • Work great and compatible with other pumps!
These are great. I ordered/use a 19mm. They obviously fit in the MomMed double breast pump, which I use as my secondary/portable pump. However, my insurance gave me the Motif Twist through as my primary pump and that pump’s flanges are only available in a size 21 mm at the smallest. And I have yet to find motif specific inserts for it. I decided to try my MomMed inserts and the fit perfect! ... show more

  • Perfect Addition
Love the wearable pump, but I found it very tedious and challenging to stack insert these in the 24mm insert, inside of the 28 flange. I picked up the 24mm flange and these are now the perfect addition. Easy to insert and they stay in place great.

  • Exactly what I needed!
I’m so happy MomMed made a standard 24mm shield! Just what I needed for my 19 mm insert instead of having to use two inserts which was a hassle to try to fit inside each other. It caused me not to really use my MomMed but now it fits perfectly and I love the pump it has great suction and I get as much out as with my Medela! ... show more

  • Awesome
I stayed away from getting a wireless pump because friends of mine were saying that they suck, but when my sisters bachelorette party was coming up and I didn’t want to miss it, I caved and decided to get these mom med pumps. I honestly wish I had gotten them sooner! I love the way that they pour the milk out so neatly and they’re so small enough to fit in a small bag and take around with me wherever I need them. Great product, thank you for making new mom life easier! ... show more

  • Easy inserts
These flange inserts are easy to use and seamed to fit into my three different pump parts easily without leaking. They are easy to clean but hard to get out of the bigger flange pieces because they suction in pretty tightly- as that’s not a bad thing just a pain sometimes!

  • Boosting milk supply
Was in the market for a discreet pump that I could wear while I’m working. I’ve heard a ton of great things all over social media about this pump and the flanges. So I figured why not give it a try. Mind you I’ve used many different pumps and no luck. The suction on this one is amazing, it’s very strong, and very quite! I am very happy with my purchase! Hopefully, this will help boost my milk supply now that I have gone back to work.. ... show more

  • Fits perfectly
Fits inside the flange perfectly. Very soft and has increased milk production and overall improved my pumping experience
