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 Nick Nigerson

These are great, I like them a lot better than the Spectra bottles.Markings are clear and easy to read (unlike the clear markings on the Spectra bottles) and they seal well and attach to the flanges without any issue. They also include a little silicone ring that you can use if they are loose.My favorite part is the caps you can write on, it works great with a regular ball point pen and comes off with just a quick scrub with the scrubby side of a sponge. So convenient and easy, much better than using scotch tape like I was with the spectra bottles.If there was one thing I'd change, I wish it had markings on two sides so you can more easily see how much you have as you're pumping. It seems like the markings are always facing my body as I pump so I can't see them without pausing pumping.
