17MM Silicone Flange Inserts Compatible with Momcozy, KISSBOBO, Lansinoh, Elvie, Willow go, Spectra, Medela Freestyle Flex, Breast Pump Shields Reduce 24-25MM to 17MM (2PCS)

I didn’t realise how important these were until I used them. I went from pumping 3oz a session to 8! Literally overnight. The difference was crazy. Any expressing mummy’s need to make sure they are using the correct size flange. These were so easy to use and ensure my pump is comfortable and effective. I honestly felt like super woman after adding these to my pump.

Good value these fit my nuillie pump and also work in my ardo pump as well

This product states that it fits the s12, however it does not fit. Also seller is pretty much uncontactable and has item set for non returnable or refundable. Do not recommend. Very disappointed

Did the job but too pricy

I personally saw an increase in my pumping output when I used these. Super easy to insert , wash and dry

Fab! Do the job they're intended for.

It wasn’t the same size as my pump

Quite flimsy thin material. I use my pump on setting 5 and it manages to such the flange in due to poor fitting. Not the greatest
