As a 'just enougher' I can express SIGNIFICANTLY more with this pump than with the Haakaa or Medela Harmony hand pump (both basically got me droplets) and abiut the same as the Spectra S1 plus, but two of these pumps plus spare parts is still less than half the cist of a Spectra.
I'm very type A, and did a LOT of research on which wearble pump to purchase, and this ticked every box.
Delivery for the pump took 2 days to metro Melbourne and spare parts got to me in about 28 hours of ordering.
Seriously effective and affordable option if you've found some of the other hand pumps to be difficult or inconsistant.
