Charlotte Y. ★★★★★ Aug 27, 2026

I was skeptical about the whole AI tracking thing, but it genuinely saves me so much time—just scan the code and my stash is updated while I’m pumping. The bags themselves are super sturdy and sealed without a single leak, even after laying flat in the freezer.

Zoe E. ★★★☆☆ Aug 23, 2026

The scanning feature is a neat idea, but it took a few tries for the app to recognize the code on the bag. The bags themselves seem durable and leak-proof, which is what I needed. It’s a decent option for tracking, though the tech feels a bit gimmicky in practice.
