I thought of buying Imani 2 but when I see the mixed reviews especially the negatives one, I went with Haakaa instead. Way affordable and no need to tire yourself to pump. Just put on your breast (the one your baby is not latching on) & it collects your milk letdown. Amazed at the milk collections the mummies had w/o pumping but just with Haakaa alone.
