This is the only pumping bra I've used and it works great with the ameda purely yours.  To all the reviewers who said it being awkward to wear at work all day, WHAT ARE YOU DOING?  Though they give you the option of wearing it all day it's really not designed for it. I wear a nursing bra to work and when it's time to pump, i snap down the nursing bra and pull up (or unbutton) the shirt I'm wearing and wrap this bra on.  Make sure your shirt is tucked back/up and out of the way and make sure your nursing bra cups are folded all the way down and you are gtg.  I'm fact I'm pumping right now!  I love the infinite adjustment!
