Eh I also pakai hands-free pump when I was working, game changer betul! Medela dan Spectra very popular among the mums in my circle, especially yang need to pump at the office, compact, quiet, and boleh adjust the suction sendiri so tak sakit. One of my friends swears by Philips Avent because the flanges fit her better and boleh charge via USB je, so senang nak charge dekat meja kerja. Try to test a few brands if boleh, sebab every boob different kan, some mums like the closed system (more hygenic for office), some prefer open. Most important is the fit of the flange and suction strength yang comfortable for you, so tak stress bila pumping.
