Both the duckbill valve and diaphragm fit my Eufy S1 Pro. The duckbill valve fits perfectly, and the top part of the diaphragm fits very snug, however, there is space at the bottom of the diaphragm, which collects milk, making it a bit more difficult to pour every drop into a bottle.It comes with 4 diaphragms, 8 duckbill valves and a sponge brush which is very helpful as you are not supposed to use wire brushes as they will tear the silicone.Overall, I am happy with this item, but I wish it fit a bit better.

When it comes to replacement parts, the highest compliment a product could receive is that the parts fit perfectly and are of the same quality as the original. These parts meet both criteria. They fit perfectly on my Spectra, and in terms of quality and material, they are indistinguishable from the parts that came in the box. This makes them an excellent value, and I highly recommend giving them a try!

Fits well and doesn't compromise suction. Nice to have affordable options when exclusive pumping requires you to replace peices so often.

A perfect match for my Eufy S1 pro breast pump at an affordable price.

I was hesitant to try non-Eufy parts on my pump, but I'm happy to report that these work as well as the originals. I have not noticed a decrease in suction or performance. The box includes 8 valves and 4 membranes, so even with daily use, these should last me several months.

I expected a pretty lame product and was pleasantly surprised to say it's moderate. A decent pickup for it's price point.

The duckbills are nearly identical but the larger ones are a bit off. They āfitā my Eufy but not perfectly so I have to find a time that Iām home to truly give them a chance. Theyāre also a bit of a thinner material Iād say. It worries me to try them when Iām not home. So I guess my input is that they technically fit but they arenāt a perfect dupe. The duckbills are though!
