Great Fit and Better Output!
Great product! I’ve gotten way more output with these valves than the ones that come with the momcozy! They fit great on my Momcozy s12 pro

Incredibly impressed!
First and foremost, I must commend you on the exceptional quality and functionality of both the silicone duckbill valves and diaphragms. They are impeccably crafted, and the silicone material feels sturdy and safe for use with my breast pump. I have found them to be highly effective in preventing milk backflow and ensuring a seamless and comfortable pumping experience. Additionally, I greatly appreciate the convenience of having a pack of silicone duckbill valves and diaphragms at my disposal. It provides me with peace of mind knowing that I have spare parts readily available, especially during busy days when time is limited. The inclusion of four silicone diaphragms is particularly valuable, as it ensures that I always have backups on hand when needed. Furthermore, I would like to commend your company for its exceptional customer service. From the moment I placed my order to the timely delivery of the products, the entire experience was smooth and hassle-free. Your team's dedication to customer satisfaction is truly commendable, and it has left a lasting impression on me. In conclusion, I couldn't be more satisfied with your 5 Pack Silicone Duckbill Valve and 4 Pack Silicone Diaphragm. They have exceeded my expectations in terms of quality, functionality, and convenience, and I would not hesitate to recommend them to other breastfeeding mothers or anyone in need of reliable breast pump accessories.

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.

Life savers for the pumping mom!
As a pumping mom, life can be stressful enough. So many different aspects of pumping are not spoken about enough. This pack of duckbill valves and membranes for the backflow protectors is affordable, fits accurately, and comes with multiple pieces of each. I have the MomCozy S12 Pro pumps as my wearable pumps, so I do not use them everyday to pump. I would say I used them 10 or so times a week. Pump parts are supposed to be replaced every 1-3 months (I am leaning toward more of the 3 months on this spectrum, which is fine and works for me!). As shown in my video, these replacement parts correctly fit my pump parts exactly how they should, and work just the same as the parts that came with the original pumps! Highlights: 1. The price: you cannot beat this price when buying supplies for breast pumps, and it comes with multiple back ups 2. Securely wrapped in a sealed bag 3. Made of silicone so can easily be sterilized for protection/safety for my baby

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.

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.
