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 Jonathan Robertson

Revainrating 4 out of 5

Great set, spring for sturdier duckbill valves

I bought these to replace my spectra parts, and all parts but the duckbill valves were great. The valves worked well for about 2 weeks, pumping 6 times a day, then they started to give out. If you need new duck bills, go for the spectra brand. A bit more, bit they last 5x longer.

Pros
  • Compatible with Spectra S2/S1 Breast Pumps
Cons
  • Difficult to use while lying down or relaxing in a reclined position
