Hi! From what I've heard, the Mama's Choice Wearable Breast Pump is quite well-regarded for efficiency, it holds up to 180ml per side and comes in 24/27mm flange sizes, which fits most mums comfortably. My friend actually uses it at her office and says it's discreet enough that she can pump during meetings without anyone noticing, which is a big plus for working mums. That said, some mums feel wearable pumps in general are slightly less powerful than a traditional corded pump, so if your supply needs strong suction, it's worth keeping that in mind. Overall, for convenience and hands-free flexibility while going about your day, it seems like a solid, practical choice.
