Flange 21mm（2PCS） Replacement,Suitable for S9/S10/S12,Wearable Breast Pump Shield/Flange Insert,Milk Collector 24mm Universal

I got these because I received a travel breast pump that had 24 mm flanges but I normally use 19mm flanges. Product is exactly as described, very soft and pliable silicone makes them fit very well in my Pumply travel pump, they’re easy to put in and take out, easy to clean and seem to be holding up perfectly fine thru multiple washes and heavy duty sanitizing. The smaller end did have the tiniest extra bit of silicone but I just gave it a tug and it came off very easily and in one piece. Def recommend if your flanges are too big!

These are great! Love that you have the availability to Make the flange size smaller for a very little price. Easy to clean!

The suctions is surprising great on this. I am an over producer, so I didn't think it was going to meet my needs, but I am happy to admit I was wrong. The suction is great, and the battery life is great. I exclusively pump and I can get 4 pumps a day on setting 2 during expression and setting 1 during let down at 20 minutes per session. Great product. However, I really need a bigger flange size. How to do I get one?

No issues with the sizing on these. They were comfortable for the most part just put a little coconut oil on the inside.

These hurt so bad, and they are not like the original mom cozy ones. They fit weird on my mom cozy s12 pro and they just hurt.. and you can not get your money back, or replace the item!! Fair warning.

The product itself is great it fit my momcozy perfectly and also was very durable I do dislike that they only go to a size 27 in flange size and I need a 28 to a 30 !! Aside from that I liked everything about it.

Pops right into spectra 2 pumps and hands free mom cozy pumps! Easy to remove for cleaning.

It’s small. Fits directly in my pump. I’m not 100% sure it works. If I had to choose what route to go, I’d probably just buy a pump in my size vs. an insert.
