I think benude will be better if you’re not those that yields 200-300ml (same for BeFree) one side kind cause the motor is attached “together” compared to BeFree where the motor is attached on top. Which sometimes risk detaching and not pumping. I’m using BeFree for 16m, pumping twice a day and requires me to charge after 2 pumps. So battery wise you have to take into consideration for Babyexpress’s BeFree pump. I don’t use benude so I can’t advise.
