The breast pump is very easy to use, at least I had no problems. It takes every time a little bit until the milk flow gets under way, but then everything works fine. I must say that my milk flows very well and I have to pump out very long never, I've heard from others who sit here forever. But this may be the breast pump nothing! A deduction of points there that the pump makes noise when pumping after a certain time. This can go one already on the nerve, because the pumping also so its takes time ... but other than that I am very satisfied.
