Momcozy Flange Insert 21mm Compatible with S9/S12 Series Wearable Breastpump, Wearable Breast Pump Shield/Flange Insert, Pump S9/S12 Parts Replace (21mm)

Glad I bought this. I didn’t realize how uncomfortable the hard plastic flange was on my spectra. After doing a quick measurement, I found this size to be work well. The softer material is also nice. The only thing I didn’t read is that there was only one, but that’s OK. I just wash it in between uses and pump one at a time.

I think it’s pretty dumb it’s only 1 flange which should be a qty of 2 since I got 2 boob*ies but whatever

If you’re like me and have S12 momcozy motors they will appear not to attach to this product. It takes quite a bit of enticing but they do fit. I promise! Once you sanitize the parts a few times the silicone does become more pliable and you will notice that the motors (over time) attach with ease.

easy to put in, milk doesnt get stuck behind it

I got these as extra pair of parts for my Momcozy s12. This is an upgraded version compared to the original one that came with my pump. It seems more study and harder to open on its own which is great so I won’t spill milk. It also does not have the hole part on the flange which makes it easier because you don’t need to align everything perfectly anymore. There’s still a whole on the cup part for you to pour the milk out. I also noticed that the duckbill valve is shorter which I think it’s because the original usually touched the cup. One of my valves arrived open which won’t get pressure and get milk out properly so I requested a replacement. But overall I have high hopes for this. I think Momcozy listened to our complains and addressed the issues.

The suction goes out sometimes on one of my pumps but the other never fails me. You can’t really bend over or hold your baby if you have to double pump. Other than that they could be quiter. They work for on the go and they get the job done.

These inserts make pumping so much better. Before I purchased them, pumping was painful and uncomfortable. Only downside is they look cloudy after washing. I’ve tried switching soaps, but they still look kinda cloudy.

It's not the same exact one that came with my S9 Pump but it works well. A little harder to put together though!
