Era justo lo que necesitaba para mi extracción de leche.

These do the job. They’re easy to work with and easy to clean. They’re also super cheap. You do not need to spend a ton of money on flange inserts. These go in easily and they work. Love them

The media could not be loaded. I’m so glad I got these today to try them out in my momcozy hands free pump, I love the fact their soft and very easy to put into place and easy to remove I also like how they lay flat inside the other flange.

Just what I needed. My nipples are much smaller than the spectra 24mm flanges that come with the pump but I didn’t want to buy different flange sizes. The measuring tool is very helpful and the extra inserts can go to friends or family members who are pumping and need them!

I almost gave this product a one star. It says it fits with a 24mm flange. For the Spectra it only fits the 28mm flange. I’m glad I tested it out because it ended up being a good product. DOES NOT FIT INTO 24mm FLANGE! I knocked off one star due to mislabeling/advertising. I imagine it wouldn’t fit other 24mm flanges either. Regardless of the brand. They should all measure the same.

If you’ve ever been in a difficult pumping situation, then you absolutely know how important flange size is the set was an absolute lifesaver for me, and I am very impressed with the quality and variety of the set. It comes with everything you need in order to find your correct size and test out the various flange sizes. If you’re having difficulty pumping, this is a great set to have in order to make sure you are correctly sized!

Not the right size

While I like that these flange inserts allow me to try out different sizes while I find the one that fits me best, it’s very annoying how they trap breast milk on the insert end because the part the creates the suction seal with the flange isn’t at the end of the insert but rather slightly behind it. This makes it hard to collect the milk drops and often times I end up spilling it. For a new mom who is developing her supply, I hate to see my milk go to waste when it could have been fed to my baby. They should improve the design of these flange inserts so that the suction seal is smooth at the edge of the insert to avoid trapping the milk.
