Nenesupply 21mm 2 pc Flanges Compatible with Spectra S2 S1 9 Plus Synergy Gold Breastpump Replacement to Spectra Pump Parts Flange Accessories Wide Mouth Work with Valve Backflow Protector Bottle

Work perfectly for Spectra S1. I always worry about not buying directly from manufacturer but was perfect. Even came with a nipple size check to ensure your buying the right size flange.

Nice product, fit for me. I would recommend this product

Has made my pumping sessions so comfortable and works great with the Spectra pump.

They perform well and generally offer suction comparable to the original pump brand parts, often with slightly stronger suction.

Exactly what I needed

These work great and fit nearly perfectly. My only complaint is that they don't screw on very tightly to the spectra bottles. So the flanges are a little loose and it makes it risky if you aren't aware of it. The flanges can pop off if you aren't careful.

I was skeptical about this in the beginning, but this is a great product. I use the Spectra Gold and have purchased both the flanges and the flange and bottle sets. It's a nice and affordable alternative to the bottles and flanges that come with the Spectra pump. I've purchased a few of them so I don't have to constantly wash pump parts multiple times in the day. As long as they keep the quality the same, I definitely recommend.

I needed to get a smaller size than the ones that came with my Spectra S2 pump so I got these. They screw on just like the original Spectra flanges and fit the bottles the same way. The only comments I have about them is that the flange opening that goes against the breast are smaller in diameter than the Spectra ones. That's really not a problem unless you have a specific pumping bra that might have a bigger opening that basically will have less flange to hold on to. It wasn't a problem for me, but just an observation. Also the material is just a smidge more opaque than the Spectra flanges, so it might be a tad bit harder to see in the flange compared to the Spectra flange. This also was not a problem to me unless I really needed to monitor the flow or I was in very low lighting. Otherwise the material was just as good and as sturdy as the Spectra flanges. They're very easy to clean, and are the same great plastic that liquid beads off of, which really helps drying time. After a couple weeks using them, I wouldn't even know they were not original parts.

Product is not as expected. It was showing 10 days replacement and now when i try to return it is showing not eligible for return. Tell me how to return this product. I am having it for no use

These worked well but I found the backflow protectors fell out a bit more easily than the regular Spectra ones.
