Review on Spectra S2 & S1 Breast Pump Replacement Kit - 27Mm Flange, Duckbill Valve, Backflow Protector Compatible W Nenesupply Parts. by Prince Burr

I needed smaller flanges as well as replacement parts, so I thought why not get the kit and save some money compared to buying everything separately? I was immediately disappointed when this arrived. The flanges are VERY short and the backflow protectors are a milky cheap plastic that do not fit very well with the membrane (which is also harder than any other membrane I have purchased?) The duckbills and hoses were fine, so not all is lost. But overall, I wouldn't recommend this kit unless on a tight budget.
