Maymom Pump Parts Incl Duckbill Valve with Pull Tab Silicone Diaphragm Compatible with Spectra S1, S2, Synergy Gold; Not Original Spectra Pump Parts; 10 pc Pink

Fit perfectly in my Spectra! I love that the parts come in a little case to keep for the next change out. I pump eight or more times a day and haven't seen a decrease in my output at all. The pulltab makes it so much easier to remove the duckbill valve, and it's PINK! Overall would recommend these replacement parts!

Works perfectly for the motif Luna

The diaphragms are nice and more sturdy than the original parts that came with my motif luna. however the duckbills are too long to fit into the spectra/motif flanges. i even tried to trim them down and there wasn't a seal, I'm so disappointed because I wanted to have duckbills with the pull tab on them. Not only are they too long, but the openings are super open (see image) I'd rather use the original so that I know it has a good suction and won't impact my already low supply.

I got tired of my other duckbills falling off these do not fall off at all. So glad I bought these!

These are great. The color is easy to see in the water when washing. They fit perfectly in motif and spectra flanges. They don’t fall out mid pump like some have.

I needed to replace my pump parts for pumping while at work. These were great and helped maintain my supply. The suction level was good. I did not have any issues washing and drying the product in my sterilizer. The pull tab duckbill valve was easy to use and it was easier to remove than the regular OEM duckbill valve. I used these parts for my Synergy gold pump.

These were as good as my spectra parts and the pull thing helps remove the duckbill super easily

These are a pleasant surprise. I've bought a few replacement kits like this and it's probably the best of the bunch. I would give this 3 stars minimum just for the convenient case they are packaged with. In the picture I did remove a duckbill for trial, you get 6 with the order.No shock, but having an even number of items is usually important. So, losing one can be annoying. A nice case makes this easy to throw back-ups into convenient spots. Travel bags, diaper bags, glove box, or night stand just to name a few. They are initially partitioned too, so you don't fling one trying to get to the other. My only compliant is you get 4 diaphragms and 6 duckbills. I guess I'd rather have equal amounts of each, but duckbills do seem to wear down quicker.I'm a sucker for companies that add small conveniences to their product. This box is just that. The quality of the parts is as good as original. They don't feel like cheap or "limp" thin rubber. I use a Spectra S2 so these are advertised as direct replacements. If that's what you are looking for then you won't find a better packaged of parts. Get it.
