I have used both the Medela "Swing" and the Ameda "Purely Yours". I ended up buying the swing as it is thesame strength as the Medela "Symphony" I used in the hospital, it is worth buying if you are pumping long term.

I have a simialr problem with my DD and feeding in public because of a nipple shield and the angle she feeds on so she has bottle of EBM when we go out.
