21mm Flange and Duckbill Valve Compatible with Spectra S1 Spectra S2 Spectra9 Plus Synergy Gold Breast Pump, Spectra Pump Parts S2 Parts S2 Accessories Replacement

These seem to be of the same quality as the original pieces that came with my wife's pump. The duckbill valves are the parts that tend to open up the most quickly and they lose their suction. It is nice that this set comes with 4 of them as they are a regularly replaced item. The flanges should give some sizing flexibility in case my wife's size changes over time (it did with the last baby). I recommend that you get a ruler specifically made for measuring flange size as it will increase supply and comfort when pumping.

I got the 19mm Flange and Duckbill Valves set to replace my original and old parts to my motif Luna breast pump. I’ve been using it for about a week now and I must say I like them! The parts fit very well and I haven’t had any problems using either one with my motif pump. The flanges fit very well and it’s nice to actually have a flange in my right size instead of having to add inserts for the correct size. I highly recommend these were decently priced and work with my motif Luna!

Considering this is only $2 more than the singular flange from the spectra website, this seems like a no brainer for me! You get two flanges and 4 duckbills for the price of ONE flange from the name brand. And quite honestly, I can not tell the difference between the flanges unless I see the name etched on the side. Win win win

These are exactly like the Spectra brand flanges. No issues so far and has been through the steam sterilizer dozens of times. Great value for the price.

I got this set of flanges and duckbill valves as i prepare again for another journey of breastfeeding and pumping. I was glad to see this set comes in size 20mm as i often find I'm in between sizes.This replacement set fit perfectly with my other spectra parts. The quality is also similar and feels just as durable. I'm glad to have this set handy and that it includes two pairs of valves as having more makes it easier not having to constantly clean so many parts.

These pump parts work well with my spectra gold. It is extremely convenient to have a second set of pump flanges and duckbills, so that I do not have to wash the parts after every pump. I can put them in a bin of water and wash my pump parts at the end of the day.I can't tell any difference between these pump parts, and the ones that came with my pump. I am very happy with these, and I plan on getting a third set so that I can just wash once a day.

I ordered the 18 mm flanges and duckbills set. I have no complaints with the duckbills, the flanges on the other hand... I noticed right away the plastic is quite thick and appeared much larger than normal. I have a set of 18 mm maymom flanges, 17 mm Idaho Jones silicone shields and 18 mm Lactek flanges and all of them seemed smaller than these ones. I can fit more of a finger in this brand. I tried to measure with a tape measure but couldn't get a consistently good measurement. I still feel they are bigger. When I pumped with this flange, I noticed some of my areola being pulled in and it was painful (despite not having any difference in suction levels and I used nipple butter as always). I had a smaller output than normal. I am not so sure these flanges are the size they say they are. For that reason I rated them thus and won't be using them.

Needed to size down as I have been pumping for over 8 months( yes you need to recheck your nipple size every month) . These work great with my maymom bottles and and spectra 2. Good quality and comfortable.* update. I have been using these for a couple of weeks now and 2 of the 4 ducksbill valves have ripped and are unusable. Docked this review 2 stars
