Flange Inserts 13mm 6PC,Compatible with Momcozy S12 Pro/S9 Pro/S12/S9 Wearable Breastpump Cup,Suitable for Medela/Spectra/Elvie/Willow/TSRETE 24mm Shields/Flanges,Reduce 24mm Down to 13mm 6pcs

Bought these to use with the Tseret Mobile pump and they fit perfectly. Just insert into the big oval shaped shield.

I used these for a year while exclusively pumping and they were amazing. They were easy to insert and clean. They were extremely durable, never splitting. I will definitely purchase again.

It does its function to perfection

These are a must have to make sure you have the right size flange when you are pumping. They make all the difference regarding comfort when you’re pumping. They fit my spectra flanges perfectly and they also fit my motif flanges but they are tighter and I have to work a little harder to get them all the way in the motif flanges.

These inserts are comfortable and effective in reducing flange tunnel size. My only complaint is that they are really difficult to get in place completely and can be tough to get out of the flange as well. This does ensure that they don’t move during pumping, but can make set up and cleaning a little difficult. They fit well in my Elvie Stride flanges as well as my Motif Luna flanges.

I’m really pleased with this product! It arrived promptly and was in excellent condition. It’s just as described, and the quality is outstanding. It works perfectly and has made a real difference. I’m thrilled with my purchase and feel it’s worth every penny.I’d highly recommend this to anyone looking for something dependable and high-quality. I’ll definitely buy again!

Perfect! They work best in a 23soze flange, but I’ve been able to use them in 20 with effort and 25 though that’s a bit big. No way in 28 they get sucked in haha but that’s expected - they’re not made for that size. I’ve used them with hard plastic flanges and silicone flanges and they work wonderfully with both.

Used as directed. The inserts wouldn't allow for a proper suction and kept rubbing my nipples awkwardly in the process. The 19mm flange itself works just fine for me. I was just trying to save some money and I think I personally may be overly sensitive. Not my first baby or time using flange inserts, but last time I didn't have such a drastic over supply and didn't need to pump as much.
