Hi,
Alot of women like th PIS,,it is farily easy to travel around with, I brought mine to and from work for 4 months straight..
I am trying the Whittlestone now,,finding it has a pulsating kind of feeling, but is not extracting any milk out yet...I have also heard the White River pump really raises Prolactin levels, I haven't tried that one yet. I used the cigarette lighter outlet in my car with the PIS, and they also have a battery pack that you can pump about 2x before the batteries die. Cathy
