Medela is great and very beginner friendly as it auto switches from massage to expression mode after 2 mins, which saves you the trouble of tracking this and wondering when to switch. LoveAmme is a good one too. It has a custom fit option, so you don’t have to worry about sizes. If you’re very engorged, go directly to expression mode. If you’re not really engorged, use massage for a couple minutes and then switch.
