Duckbill Valves for Medela and Spectra, Tinabless 6 Count Pump Duckbill Valve for Spectra S1 Spectra S2 Valves and Medela Pump in Style Valves

I like these much better than the flaps that are used on the medela. couldnt really tell if it pulled a lot more milk, but the ease of use was great and less parts to clean.

These work very well with my medela pump. I prefer these over the classic valves that came with my pump. much easier to clean and less small pieces to lose. I also feel like I pumped more milk but that may be a coincidence.

The suction on them is not good. I used then once and they became detective. The funnel part of the duck bill is much thinner than the original duck bills I have for my spectra.

Great valves! Better than the yellow ones, and this comes with a case to hold the ones you aren't using.

They work for the spectra. However they are kinda thin at the bill. I’ve been using them for almost a week and have had no problems so far but I wouldn’t be surprised if they ripped.

Works great with my Spectra S2!

The media could not be loaded.  Out of all 6, only 1 seemed new. All the other ones are defective.

These were a great addition to our setup. They fit both styles of pumps my wife has. They are holding up nice and it is very convenient having more than two!
