Great replacement parts for a wearable pump!
I purchased the momcozy wearable s12 pro pump with my own money, so I was not receiving replacement parts from insurance. These replacement parts are enough to make it feel like a new system! They fit well and wash easily, and are a great value to improve the functionality and lifespan of my wearable pumps.

Works with my pumps
I originally ordered these to use on my momcozy S12 but I ended up using them with my hand pump (evenflo brand) and my wall pump. They are pretty universal and they actually worked better and stayed out better on my momcozy! The duckbill that originally came with my momcozy kept sliding off while I was pumping no matter what I did (I only used it 3 or 4 times before this) I popped one of these on and it works a lot better and stays put. Also easier to cle.

Highly recommended.. MINUS the packaging!
First of all if you are a stickler for packaging this isn’t for you.. box is taped shut with scotch tape sooo. However, the product itself seems pretty great quality at affordable price point. This was purchased for my mom cosy and the peaces worked well with it. I’ll be keeping and would recommend.

Zomee Hands Free Collection Cups
Duckbill fits Zomee hands free collection cups but the diaphragm does not fit the hands free collection cups - still a better deal to buy this package for multiple duckbills for the same price as Zomee brand 1 set of duckbills

Necessary to keep on hand
If you pump you need this on hand. When the pump is not pumping correctly, it is a good chance one of the duck bills or diaphragms has weakened. Ans when you pump you need these parts on hand because you can not wait a couple of days before relief.

Ordered these in a panic when I got a small tear in one of the duckbill valves from momcozy. These are perfect! I have the s12 pro for reference

I have been struggling to express much and didn't think about replacing the parts. Get alot more milk now and they fit perfect with my momcozy s12 pro.
