I would save your $$
I bought two different kinds of hands-free (single units). I wanted to make sure I could wear something on an airplane and couldn't trust one brand from another. Obviously my normal spectra pump works best and can help yield about 2oz from each breast. But out of the 2 hands free I got, this one performed the worst. After 20 mins of painful pumping I had less and an ounce to show for it. Very disappointed. Glad I only bought the one and not both. It doesn't help that the nipple shields for these pumps are so massive, it just doesn't help the majority of women who usually measure much smaller then 24mm sheesh.
