I used the Motif Luna. I was a massive underproducer, but got more with that one than the Medela Pump in Style with maxflow.

Spectra is okay. Nothing wrong with it whatsoever. It was my trusty go-to for a year of exclusively pumping and helped me build a substantial stash. However, the Zomee wearable pumps are way more efficient for me. I can get the same output in half the time with the Zomee.
