Breast Pump Flange Insert Compatible with S9/S10/S12 Wearable Breast Pump Accessories.Wearable Breast Pump Shield/Flange Insert Replacement. S9/S10/S12Parts Replace (17mm-2Pcs)

My friend had boughten me the momcozy portable breastpump. Sadly it did not come with the right size flange for my breast. I had to order these and pray they'd work. They work amazingly

So I am over the moon, I bought the fetalplus hands free pump, and it came with 24mm silicone shields, however they do not sell bigger sizes I found out and I need 27mm shields, so I decided to try these and THEY WORK!!! I was so nervous to purchase because I was afraid they weren't going to fit, being no one say compatible with the fetal plus 3.0 pump, the only thing I had to do is cut the slit just a tad bigger for it to seal properly, and like magic works perfect. For any other moms that have the fetal plus get these and the small modification, it works great has same suction/ seal power thank you so much! I'm so relieved to not have to buy a whole new set up!!!

Great product for the portable breast pumps

Compatible with my momcozy s12. And a lot cheaper than the actual momcozy ones.

I needed a size up but unfortunately these were alittle too big tried to return but turns out I am not able to do so which sucks for the price we pay

The product was better than I expected, the quality was great and they were able to get the job done!

This worked great for my momcozy s12, I was looking for a 27mm option with the pour spout and this was exactly what I was looking for. It does only come with one flange so you will need to purchase two.

Edit: I’ve been using these for about a week now and have gotten used to them. You do need to be extra sure they are aligned exactly right to the internal flange on the S12. I haven’t noticed any issues to the base of my nipple since the first time I tried these.Old review: I was looking forward to having these in a size 27mm for the Momcozy S12pro. It does fit however, there is a very slight (but sharp) gap between the flange and the internal plastic of the nipple hole. With first use it created a ring around my nipple at the base and tore some skin. I’ll post and update for later as I plan to use them again to see if it persists. I bought four as I have two pump sets to make is easier for night time use (less cleaning). I probably should have waited to get four.. It holds the milk though and will do for now. Better than having nipple bruising from a tight flange I suppose.
