NENESUPPLY6 pc Duckbill Valves Compatible with Medela and Spectra Pump Parts Use on Spectra S2 Spectra S1 Pump in Style Harmony Symphony Replace Spectra Duckbill Valves and Medela Valve

I bought these as backups for my Spectra S2 pump, as I am worried that the original valves that came with my pump might tear, get lost, or degrade over time. These valves fit perfectly onto my Spectra S2 flanges. They are actually easier to put on and remove compared to the original Spectra valves. They seem to provide the same amount of suction and efficacy as the original valves do.I am glad I bought these since they are cheaper than original Spectra parts. I LIKE THESE BETTER THAN THE ORIGINAL SPECTRA S2 VALVES! Strongly recommend.

I exclusively pumped for over a year and made sure to have enough pumping supplies that I did not have to do dishes after every pump. That meant I purchased a lot of replacement equipment and was always looking for the best value. I purchased Spectra duckbills for a while and eventually switched over to these.The look different than the spectra duckbills, smaller. They work just as well and since I replaced duckbills almost monthly, these saved me a lot of money. These were pretty resilient and held up to the washing. I would definitely suggest these.

Great price, great item! I am impressed with how easy these are to use and how cheap they cost. it is a great value -- I exclusively pump for my little one this time, and these have been needed to be replaced more often than not. So, its been really good and helpful to have a little set lying around just in case if I need to replace the part. Great value!

I'm on my 3rd baby and have pumped a lot with all 3. I quickly switched to these after the yellow and white Medela ones crapped out within days/weeks of pumping with baby #1 and i havent gone back. These have way better suction and don't warp easily like the medela ones. The only "flaw" I've seen is that with this baby I noticed a few that I bought originally (almost 5 years ago) that were getting tears near the opening where the milk comes out and it wouldn't allow suction but these had seriously been used for hours and hours and hours of pumping before this occurred... and it may be more my fault because I always scrape the opening on the mouth of the bottle to get all the drops out before storing the milk. Fantastic product. Highly recommend.

These work fine, they’re nothing special. I pump 3 times a day and just need to last two more months to make it a year so didn’t want to spend a ton. These work okay and I don’t notice any suction issues, but they make an obnoxious squawking noise like a duck call or something. Or a red nose on a clown. It makes me laugh!! Thankfully I work from home but if I was pumping in my office with the door shut my coworkers would DEFINITELY hear this. It does make it hard to make phone calls or anything while you’re using it, but whatever. They work.

I bought these to replace the originals that came with my spectra s2 & the suction is SOOO STRONG! stronger than the originals. Have only used for a day and my milk output has already increased!

They work. Easier to clean than what comes with breast pump. Unsure if I pump any different with this than with other valves. I have only used this style of valve.

I was having trouble with the Medela valves, too many parts to trouble shoot when suction is not working and definitely not ideal when I use my pump while driving on my way to work. I was a little hesitant at first to use these duckbill valves but they are the best decision that I made. Although the base is a little stiff it is overall very easy to clean and the suction is so much better. I strongly recommend them.
