Is a wearable breast pump strong enough to be a primary pump?

Across specialist communities like r/ExclusivelyPumping, the consensus is that most wearables are best used as secondary or on-the-go pumps. A subset of users do report using wearables like the Momcozy V1 Pro or Paruu models as a primary pump successfully, but yields are typically lower than a plug-in hospital-strength pump like the Spectra S1 or S2. If you're exclusively pumping, most reviewers recommend keeping a traditional pump as your main and using a wearable for convenience.
