Kudos to Ann with regard to her statement about ROSS.  I have but one thing
to add...

     Through my many years of assisting breastfeeding moms, it has become
apparent to me that Formula company breast pumps were developed for the
distinct purpose of sabbotage.  None of them have descent suction.  The whole
purpose of their existence is for women to try pumping once and turn to the
bottle...

     Just like the Hosp. Formula packs and the cases sent during pregnancy,
these pumps lay on drug store counters, waiting for the unsuspecting new dad
to arrive just before closing time...                  Debbie Albert, IBCLC
