The universal flanges that come with the pumps don’t work for everyone. These flanges help tremendously.

True to size!

The media could not be loaded. Work awesome! It made me feel better for looking for the right flange size without paying more. Cause pumping can get pretty pricey after a while. Still cheaper than formula though!

Bought for momcozy m5. Only issue I have is that the tube part is long and the only way to pour milk out is to remove the flange. Otherwise works great.

So glad I got this. Increased my milk production a few ounces on my portable pumps. Definitely have recommended to others!

I brought this kit not really knowing what size I needed, I was still trying to figure it out. I was working between 17mm & 19mm. While 17 gave me a good output, after a few uses it was leaving my nipples more sore than the actual pump. 19 gave me good output with a lot less pain. 17 was too small, 21 was too big and 19 is just right. Since getting this, I’ve went ahead and purchased the kit with 4 pairs of 19mm silicone flanges. Great purchase and I know the longevity is worth it.

I got the momcozy S12 pro through Aeroflow and as soon as I got it I realized I’d need a different size flange than what came with it. The Aeroflow website only allowed you to order individual sizes and I wasn’t 100% sure what size I’d need and I know they can change throughout the breastfeeding journey so I wanted to try and find a multi pack. Amazon to the rescue! These fit and work perfectly with the Momcozy s12 pro and it’s all of the sizes you could possibly need.
