Review on Spectra S2/S1 Breastpump Backflow Protector Connector By Nenesupply - Compatible With Spectra Flanges by Nick Moo

Lansinoh makes this style flange body for their pumps which is effective as it's easy to hold. These are far lighter than Lansinoh's. Now these bodies do work and is a much better design than the original spectra style. Spectra flange is cumbersome to hold. Grateful there is aftermarket items like this functional item that makes pumping less of a drag.Pumpin' pals flanges do work with the bodies however they are a little loose at the base. It's not a problem since I normally hold mine and don't move around when pumping.Threads seem stable so far and no leaking. Overall for the moment, great buy.
