I would have loved to get a hold of one of those new pumps.  I am
skeptical about it truly being a closed system, as stated. If there is
any positive pressure being generated via the motor to the breastcup
there will be a positive exchange of airflow, along with a negative one.
This in turn can mean contaminants can be pushed away and towards the
breast. This is the way all of the current hospital grade and home use
models operate. If anyone has a gauge they can measure the spikes and
see if the gauge moves in both directions while cycling.
