The Philips Avent Double Electric Breast Pump features a unique design, so your milk flows directly from your breast into the bottle or container, even when you are sitting up straight. This means you can sit comfortably when pumping: no need for you to lean forward to make sure all your milk ends up in the bottle. When switched on, the pump automatically starts in gentle stimulation mode to get your milk flowing. There are 3 pumping settings to choose from.
