spectra s1 vs medela freestyle

Bottom right with the human on it Is default pumping. You can set it to your favourite speed then press and hold on the bottom right to save your it to your default. So next time when you switch it on can just straight press the human button.

The one on the left is to massage The one on the right is continous pumping Once u on it, it will massage for a few mins then it will change to pumping. If u feel the pressure not enough, u can increase it

It's OK to not touch those 2 buttons. If you press the middle start button, it will be in stimulate mode for 2 minutes (fast pumps to stimulate milk production) then will automatically switch to actual pumping mode. If your milk already comes out before 2 minutes, you can press the left button to switch to pump mode. During pumping if the milk stops coming, you can switch back to stimulate mode for a minute then back to pumping. The right button I've never used but seems like it's pumping in the lowest strength level.
