Maymom Duckbill Valves Compatible with Spectra S1 S2 9 Plus Dew 350 Not Original Spectra Pump Parts S2 Accessories Replace Valve (Orange, 4ct)

I love these.They work so amazing with my pump.Even they're not exactly made for my pump.They still work phenomenal there pretty cheap.They are so heavy, which is really nice.Cause they are not wearing down anywhere near as quickly as my others love them. They have been such a lifesaver , and they make it feel like my pump gets more suction with them

These duckbill valves work perfectly with my Spectra breast pump. They come in a pack with many, which is super convenient so I always have spares on hand. The suction is just as good as the original Spectra valves, and so far they’ve held up really well after multiple uses and washes. Great quality and value—definitely recommend for any Spectra pump user!

I prefer these over the valves that came with my pump! They work great just as long as you replace them when needed!

Works perfectly with my spectra! No complaints

Nice and sturdy and a great replacement for my spectra pump!

If you’re REALLY on a budget, these will work, but I’d recommend just paying the extra $10 for a two pack of brand name Spectra if you can. They fit okay, but the base isn’t long enough to completely fit the height of the output spout in the flange. And the diameter may be a millimeter too small, because mine wrinkle slightly when they’re on. Not enough to completely break the seal of the valve, but enough to affect it. The silicone on the valve itself is a bit thicker than on the brand name, which makes it more sturdy, but also more clunky and less finely tuned. Where the spectra feels like a thin membrane that will open at the slightest amount of milk, the maymoms feel more like the thickness of paper and more milk will be left behind. Furthermore, I can hear the seal breaking slightly when the suction is on, like it’s not a perfect fit. Whether it’s because of the wrinkling, the thicker valve, or the short base, air is definitely moving somewhere causing the suction to be slightly less powerful. Doesn’t affect my pump all that much, but could be a problem at higher suction levels if you require them.

I feel like these last way longer than the name brand spectra duckbills, I just ordered my second replacement duckbills and I am very happy how my previous ones lasted way longer than my spectra duckbills.

I needed more duck bill valves for my spectra, these have worked great, they’re compatible with my flanges that I already have. They wash and sanitize well. I think they work better and have better output for me than the ones insurance has been sending which are super cheap. Also it was awesome to get several sets for such a low price. I appreciate these came with a little case too! I will definitely be reusing the case even after I’ve used all the valves.

Works perfectly with Medela Harmony hand pump as it creates more suction

I purchased these for my spectra s1 and they worked a treat. Great quality and value for money.

They perform their work, but you can notice they are not as good as the original

I really like these colourful valves so that you can tell which pair is new and which pair is old. they do the job well. however, compared with OEM ones are only $5 after tax per pair including tax if I purchase in Asian countries, the price in North America is much higher! but considering this is Korean brand, it make sense it's expensive here. No complain then!

Parfaitement compatible avec le spectra S1.
