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.
