This two-piece set targets moms using Spectra S1, S2, and 9 Plus, as well as select third-party models like Motiff Luna and Ameda Mya.

What it is and how it helps

It pairs with Spectra valves and backflow protectors and can be used with Spectra wide-mouth bottles, as well as AVENT and Momstouch wide-mouth bottles. The wide-mouth design is intended to support a secure attachment and steady operation, without asserting specific outcomes.
