## Questions & Answers

**Q: Is there 2 per order?**
A: Yes. 2 pcs are included.

**Q: Can you use standard spectra duck valves on the flanges? Or do you have to buy this brand to replace**
A: Yes but i returned these and bought maymom. The designed its flawed leaving milk to leak if you tilt while pumping in anyway this is because the bottle doesnt screw in all the way it leaves a space which is senseless because sometimes mothers have to squeeze and pump at the same time which makes us tilt the bottle by accident.

**Q: Can this be used sign the Ameda Mya pump?**
A: I’m unfamiliar with that pump. I did buy an adapter to fit these on the medela bottles.

**Q: Do these fit MAM bottles?**
A: No. But they will fit Phillips Avent bottles.
