As a mom who's been through the pumping journey, I can confidently say these LOZAEVE 22mm flange inserts are a lifesaver. The compatibility is insane – they fit my Momcozy S12 Pro, my friend's Spectra, and even my sister's Elvie Stride. No more buying multiple expensive brand-specific flanges!
The multi-size options (11 sizes!) are perfect for fluctuating nipple sizes during different lactation stages. I personally cycled through 3 sizes in my first month postpartum. The transparency of the silicone makes it easy to monitor nipple alignment – a feature I didn't know I needed until I tried these.
While they're durable and easy to clean (just toss them in boiling water), I did notice a slight chemical smell initially that faded after a couple washes. The packaging could be better – mine arrived slightly squished but thankfully not damaged.
The real win? These helped me identify my perfect flange size after weeks of painful pumping sessions. My output increased by nearly 30% once I found the right fit! Just be sure to check all sizes are present when you receive them – one of my orders was missing a pair.
Pro tip: Use coconut oil with these inserts for ultra-smooth sessions. And yes, they do shift occasionally in wearable pumps if not inserted deeply enough, but at this price point compared to brand-name options, it's a compromise worth making.
