Made my life so much less painful!!
Definitely worth the money! Having multiple size flange inserts that worth with both my Medela and Lansinoh pumps is wonderful. Being able to pump without the overwhelming amount of pain from the incorrect flange sizes has been such a relief. Using the sizing guide to measure and having the correct flange inserts in the kit along with the sponge thing to clean them has made my life so much more comfortable, as well as easier. I’m not struggling as much to empty completely anymore. I gave some of the smaller sizes I didn’t need to a few moms in the NICU that were going through the same thing after they measured themselves. I had originally planned to donate the sizing guide and leftover flanges to the lactation nurses to help them better measure other moms in the NICU however they couldn’t take them.

Love this
This is a great kit for first time pumping moms who need direction on flange sizing. The ruler helps you find your size. It includes lots of flange inserts to get your perfect fit which is very convenient. Instead of having to then order the correct size you already have the options in this kit.

Definitely worth it!
If you’re on the fence about ordering this, definitely do it! It fits perfectly into my medela hand pump, the flange inserts into the flange that it already came with it. The first picture shows what I’m explaining. My hand pump came with a size 24mm and I’m a 19mm so definitely a huge difference. It actually doesn’t hurt when I pump now and I get more milk too. Not expensive and made well! Very comfortable too.

Very well organized nipple sizing set
These work great. Not sure if it’s Increasing my milk, but it’s doing its job. It lets you know what size the nipple is as well with the measuring card. It fits into my medela hand pump.

Good product, very poor packaging
These inserts are good. A little hard to get into the flanges but do making pumping more comfortable. I like the ruler but the box is too small and it was all bent. I was also sent the wrong color and the box was damaged. Including a storage box or bag with this kit would be helpful.

Pumping game changer!
Absolutely changed the way I was pumping! If I could have put one thing on my registry for personal items, I would have added this. The flanges made such a huge difference in the way I was pumping. All the flanges are super soft and fit right into the breast pump. I personally used the spectra 2 and had no issues with it. It comes with a convenient little brush to clean them after use. The sizer that comes with it as well is easy to use to know what is the right size for you. Each baggie is also labeled as well so there’s no confusion which helped a lot and there’s many different sizes.

Loved this kit!
LOVED that it came with a ruler this helps so much as my body makes changes and I’m able to find out easily what my flange size is to get maximum output for my pumping sessions.

Comfortable, works well enough, but not see through like advertised
These are comfortable, I found the right fit for me and I no longer cringe when I turn my Lansinoh pump on. Lining up my nipples can be a bit tricky though because these are not see through. Had I known they were opaque, I probably would have bought a different set.
