Heavy Duty Breast Pump Vs Medium Duty Breast Pump

Hello, mummies! Nak tanya, apa beza heavy duty dengan medium duty breast pump? Working mom here and planning to be an EP mom so akan heavily use breast pump. Saya ada beli Arley Z10 Ultra. Rasa nya kalau wearable breast pump ni category medium duty ya? Ada hajat nak beli hospital grade pump contoh macam Spectra S1 @ Spectra Dual S. Ada sesiapa guna Spectra? Boleh bagi feedback? Atau ada cadangan lain selain Spectra? #firsttimemom #advicepls
