I have had one experience with this pump.  A client tried to use it to maintain
 a supply while at work and found that supple dropped.  When we tried to set he
r up with a double pump I found that the flange from the little pump was not
 compatable with the rest of the company's supplies  So we had no instructions
 on use and a cost almost as much as the mini motor and a flange that won't fit
  anything else.  I am worried moms will think this is great pump for work and
 that we will lose them to low milk supplies.  They need guidance in selecting
 the right pump for their needs.  I have hundred of moms working and keeping up
 supplies--I want to keep it that way.
