A little bit more info...

• Medela's 2-phase expression powers the Swing Maxi by mimicking the natural sucking motion of a baby.  It starts off with quick patterns to stimulate the breast and then followed by longer ones to provide your baby with optimal, consistent milk flow.  The other benefit - you express faster so your baby is happy and we can imagine you will be happier too!
• The benefits of simultaneous double pumping are massive.  You ensure you always have adequate breastmilk available for your baby as you will produce 18% more milk than a single breast session. The milk has higher energy content and you will be saving twice as much time - how great is that!  PS: you can always switch to single breast mode if you like.
• The Swing Maxi is premium machine and provides you with numerous settings to adjust the vacuum level to make sure you are comfortable at all times.
• Every part of the Swing Maxi that comes into contact with your breastmilk is completely free from any nasty BPA.  
• Super easy to assemble and clean.  You can clean, sterilise, boil, disinfect each part to ensure a bacteria free breast pump
• Every woman has a different breast size and therefore needs the perfect fitting breast shield to ensure effective pumping sans-pain!  There are 5 different sizes of Medela's Personal Fit breastshield.
• Great for moving around with it's light construction. Never fear - you can use batteries or a power adaptor so no matter where you are, your breast pump is ready to go.
• Nice and quiet like breastfeeding should be
