I was skeptical that a portable pump with cups would work as well as my spectra but this pump is awesome! It’s not too intense for my elastic nips and it empties me just as well. It’s also perfect for popping in my bra and getting stuff done around the house (no full bending but pretty good range of motion) while I’m pumping so I’m not tied to the wall for 30 minutes. I even overflowed one of the cups while driving because I didn’t really think it could empty me that well!
If there’s any room for improvement I’d suggest not starting automatically on level 3 instead of level 1 and I’d add a tiny flashlight on the end (where the charger cord goes in) so I can take a peek in my bra while the pump is running.
