Flange Insert 13/15/17/19/21mm 10PCS Compatible with Momcozy S12 Pro/S9 Pro/S12/S9/Medela/Spectra etc Electric Breast Pump 24mm Flange/Shield, Reduce 24mm Tunnel Down to Correct Size

Love that it’s different sizes in 1 box and comes with a sponge to clean them with. They also fit in ever flange which is nice

I like that it has a lot of size variations. Great for the price and it works for my spectra.

Excellent quality and great fit for my portable pump. Increase my milk supply due to having improper fitting when pumping.

These helped me tremendously. I was not getting much output before ordering these. Got my correct size and was able to test them out and got much more milk out!!

Very convenient for pumping, down side would be that they feel just a tad loose when inserted but they get the job done

The material of these silicone flanges are soft and gentle on my daughter's skin, making it comfortable for her when she is using them. The different sizes help her to choose which one she needs and then the correct one provides a comfortable fit, ensuring efficient and pain-free pumping. They don't cause her any irritation or discomfort, allowing her to focus on expressing milk without worrying about soreness. So far after several uses they have withstood regular use and cleaning without losing their shape or effectiveness. A very nice set for pumping moms.

I've used these with multiple different pumps. Very versatile and works as expected. Included sizing tool was extremely helpful in determining size needed

The item itself works fine but I bought this specific brand for the carrying case that appears in the review pictures. Mine did not come with a carrying case, all the parts were just loose in a box. I probably would’ve gone with a different brand had I known.
