1pcs S32 Breast Pump Milk Collector Cup Compatible with NCVI NICEGREEN Nuliie Zooawa Sunnaltree s32 Wearable Breastpump, Collector Cup Replacement Breast Parts for S32 Pump

Works great and fits into all my pumps!

These are a great affordable option for replacement pump parts! They fit perfectly with the Eufy S1, and I actually like the diaphragm piece that comes with this better than the standard Eufy one! If you use the Eufy pump as your main pump, a couple sets of these should last through a whole year of pumping! I’m 6 months PP, and just bought a second set. The silicone of these seems to hold up very well!

They really work great! My pump seems to have better suction now too! Perfect fit!

Save your money and get something else, the duckbills all came in with big gaps and did the water test and obviously they all vails the water went right through then decided to try the diaphragms and barely got any milk out, put on the old og one and got 5oz out, also milk was leaking out of the top of the diaphragm!

Great quality for a good price, I like having different sizes in the pack because even after 1 kid I still wasn’t 100% sure my flange size so this allowed me to play around with different sizes to see what worked, turns out I was still using too big a flange last time lol

Does the job

Absolutely perfect for hands free pumps!

A cheaper alternative than buying the name brand from the breast pump manufacturer website. Unfortunately, all but 2 of the duck bills had gap openings meaning the suction won’t be as strong or effective. It’s great to get the item fast, but the quality of the items are subpar considering over half of them didn’t provide proper suction.

Absolutely shocking, suction has not gone from duckbill valves, they have huge holes in, had to order more as my pumps are no longer working properly
