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 Jeff Bruno

I'm a near-exclusive pumper, so I go through a lot of bottles. My pumps are the Spectra S2 (wide neck) and Medela Symphony (narrow neck) and I have a bunch of Avent bottles (wide neck), so the two things I need are (1) narrow-to-wideneck connectors, and (2) extra wide-neck collection containers.I've tried both the MayMom and the Matyz collection containers and connectors. The MayMom parts are a little more expensive but, IMO, worth the extra cost. These collectors fit my Spectra, Avent, and Matyz lids and flanges perfectly, and the MayMom lids fit containers/bottles from Spectra, AVent, and Matyz perfectly as well. In contrast, the Matyz lids/connectors do not fit the Avent or MayMom bottles/containers well and kind of have to be forced on.So my recommendation is to pay the extra money and go with MayMom on these.
