Nenesupply 2 21mm Flanges Compatible with Spectra S2 Spectra S1 Spectra 9 Plus Pump. Replacement Parts for Spectra Pump Parts Replace Spectra Flange Made by Nenesupply Not Original Spectra S2 Parts

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

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

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

They work just as well as the regular spectra flanges, the only issue I have with them is milk dripping from the screw on part, it's definitely not a good seal no matter how tight you screw it on

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.

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.
