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 Mike Martz

Let me start by saying that before choosing a pump I did a ton of research and read a ton of reviews, and Spectra was the clear winner with the biggest con being that replacement parts are not easily available by being sold in stores. So the first time I needed a replacement, I ordered directly from Spectra. They shipped fast and no issues. Finally decided I needed an extra set of parts to save some sanity on washing parts and decided to try these. I was a little concerned because some reviews said they were not interchangeable with the spectra pieces. These replacement parts are just as good if not better than the originals from Spectra! And for half the price. Plus, the customer service is amazing! A++! Not sure why I waited so long to get an extra set of parts. What a lifesaver. And with these being amazon prime, it's just as good as being able to run to the store for parts! (Except with a baby no one wants to run to the store anyway).
