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 Adam Wilson

So glad I finally replaced my original spectra parts with these. They’re better quality than the original parts. The backflow protectors would always squeak when I tried to remove them from the flanges and would startle the baby. It was so annoying. These just glide right off. The valves are better and help provide a little stronger suction as well. I will definitely be ordering from them again
