I just got a freestyle pump (was using a borrowed older pump in style), and I'm not getting anything out. My old pump didn't have the 2 phase let down thing; just manual adjustments for suction and speed, which I kept at the middle. With this new one, it seems like it's not as effective.
Does it take a while for my body to get used to it? It's annoying, because it feels like this is less powerful overall, and I paid a ton for it, and there is no way to return it.
