Review on Maymom Wide-Mouth Milk Storage Collection Bottle With SureSeal Sealing Disk; Compatible With Spectra/Motif Luna/Ameda MYA/Bellababy Pumps. Can Replace Spectra S1 S2 Bottles, 6 Pc (4.7Oz/140ML, 6Pc) by Paul Walters

LOVE these. I use them with my Spectra S2 and i like them so much better than the spectra bottles. The measurements on the spectra bottles are way off, and these are much more accurate. The lids are awesome. I love that the caps fit in tightly so they dont slide back apart like the spectra caps. Its like its one solid piece. Most importantly i love how versatile these are. My baby uses Avent bottles, and i can just put the lids/nipples right on these bottles and feed straight out of them. I actually considered purchasing a set of the larger bottles as well, but then i realized i can just use the actual avent bottle when i know i will pump more than usual. When you are constantly pumping, every tiny bit of convenience means everything. These save me lots of annoyance, and its one of my best purchases in a while.
