WORTH THE PRICE to get every last drop
Doubled my output immediately. I had a 2 or 3 week window of continued decrease in milk supply and my old "knock off" valves were sputtering bubbly milk. I knew something was off- I tried herbs, more water, less stress, etc etc. It was my crappy old valves. I bought these and immediately had 2x what I was getting out that very morning. There was no sputtering. Just smooth streams of milk and pure gratitude on my end! Absolutely worth the cost.

Just what I needed
Works well with my spectra pump and have had for a couple months now and with rotating the valves, I’ve noticed that I don’t have to replace any yet. I pump on average twice a day for 39 minutes each time.

Great- worth buying these named Brand duck bill valves
Recommend theses Spectra parts over non-named brand. They seem. To fit much more securely to create improved suction.

Very helpful and easy to use.
This breast pump helped me so much during my breastfeeding journey. It’s comfortable, easy to use, and made pumping much less stressful. It saved me time and really supported my milk supply. I’m very thankful for this product and would recommend it to other moms.

Would buy again if needed
Good quality. Fit on my breast pump as intended, but seemed to be just a tad different than the original ones. Still able to use them and would buy again, but just know they aren’t exactly the same size.
