Maymom4 Count Duckbill Valves for Spectra. Designed for Spectra S1 Spectra S2 Spectra 9 Plus Spectra Dew 350 Spectra Pump Not Original Spectra Pump Parts Spectra S2 Accessories Replace Spectra Valve

Works great, replace every few weeks

I've looked at a few of these to replace parts on the spectra breast pump my wife is using and these are the best alternative to the brand product in terms of quality and price.They seem a bit thicker and less flexible than the original parts, but it hasn't made a difference in the pump performance.Expect some milk to get stuck in it when you turn the pump off.Good product.

I really like these colourful valves so that you can tell which pair is new and which pair is old. they do the job well. however, compared with OEM ones are only $5 after tax per pair including tax if I purchase in Asian countries, the price in North America is much higher! but considering this is Korean brand, it make sense it's expensive here. No complain then!

So much cheaper than the extortionate name brand price! Fit my Motif Luna perfectly and instantly improved pumping productivity compared to my worn out valves. The different colors are a big plus for keeping the sets straight so I know when to replace a pair (exclusively pumping runs through these quickly). They're a nice snug fit which makes them tricky to remove to wash but worth it for the improved suction.

Great fit. Great material. Really good value. Easy to clean.
