Review on Nenesupply 21Mm Flange Replacement Kit Compatible With Spectra S2/S1 Breast Pumps, Including Ducksbill Valve, Backflow Protector, And Other S2 Accessories And Parts by Jeremy Kakaruk

I bought these because I couldn't afford the name brand replacement parts for Spectra. I had my misgivings due to some of the negative reviews saying the suction doesn't work as well and they noticed a drop in supply. Not the case for me! In fact, the suction feels much stronger than what I experience with the name brand Spectra parts - I was used to having the suction power at a 10 or higher and the cycle at 54, but with the Nenesupply parts, I have the suction at 8 or lower and the cycle at 46! Needless to say I'm very pleased with this product and will be buying again when it comes time to replace my parts.
