As a mom who's been through the pumping grind, I can confidently say these replacement parts are game-changers. The first time I used them, I was shocked at how identical they felt to the original set—no awkward adjustments or leaks. The 24mm single-sealed flange creates such a secure fit that I actually get 0.5oz more milk per session compared to my old worn-out parts.

My favorite feature? The thoughtful full-set design. One midnight when my baby decided to cluster-feed, I grabbed this pre-sterilized set instead of facing a sink full of dishes. The valve and diaphragm worked flawlessly while binge-watching Netflix in bed—no drips, no fuss. Though fair warning: like another reviewer mentioned, the duckbills do need replacing every 3 months (I mark my calendar now).

Pro tip: These work surprisingly well with my Spectra too! The tubes require a firm push to connect, but once secured, they perform just as well as my $50 wearable cups. For moms who hate being tethered to an outlet, this is your ticket to mobile pumping.

The only minor drawback? The lip design differs slightly from OEM parts—took me one try to get the angle right. But at this price point, having backup sets means I'm never caught mid-pump with malfunctioning parts again. These live permanently in my diaper bag and office drawer now.
