any mummies using the silicon manual breast pump? heard that it's not very ideal as may hurt the breast etc... as I'm considering to get one and put in office.

hmm.. I've asked around and one of my friends was using Pigeon Manual Breast Pump. Works well and she did not have any complaints about the pump itself. However, she switched to an electric pump shortly after as she realized manual pump took longer and she wanted to keep the pumping session at work as short as possible.
