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.

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
