As a mom who's been through the pumping journey, I can confidently say these LOZAEVE 22mm flange inserts are a game-changer. The compatibility is insane – they fit my Momcozy S12 Pro, my friend's Spectra, and even my sister's Elvie Stride. No more juggling multiple flange sizes!

The multiple size options (11 sizes!) saved me during those early postpartum days when my nipple size seemed to change hourly. The transparent food-grade silicone is not only safe but lets you monitor positioning – crucial for avoiding those painful pinches. Though fair warning: one of my sets had uneven size distribution (3 of one size, 1 of another), so double-check your package.

What really won me over? The comfort difference. After struggling with standard 24mm flanges, these inserts helped me discover my true 18mm size. My output increased dramatically and those awful friction burns disappeared. They're thinner than hospital-grade inserts but still effective – just push them deep into your pump shield to prevent shifting.

The cleaning is effortless (warm soapy water does the trick), though they do have that distinct new silicone smell initially. While the packaging is bare-bones (think crammed in a tiny bag), the value is unbeatable compared to name-brand alternatives. As a first-time mom, these were my pumping lifeline – helping me find my perfect fit before investing in permanent flanges.
