Review on Maymom Wide Neck Breastmilk Collection N Storage Bottle 5.4 Oz; Re-Markable SureSeal Disc. Compatible With Spectra S2 Spectra S1 Spectra 9 Plus by Levi Stewart

These bottles are the best! I bought the 4.7oz size as I typically don't get that much milk during each session to justify buying the 9oz size. I pump at work so I have to transport milk and was having issues with spillage with the bottles I was using before. I also don't have a tall cooler so these bottles are great and don't have to worry about spillage. Even if they get knocked over they don't leak and I have the bottles with the 2-piece cap. The sealing discs are awesome being able to write on them. I was skeptical about them washing off if you used a ball point pen but they do once you run it under water. I also use a Spectra s2 pump and I haven't had an issue yet with the bottles becoming disconnected with using the sealing disc. The Avent nipples do fit with the ring. If you purchase these bottles you will not be disappointed.
