@ jo: sorry did not reply you, yes I have received, thank you so much for your info! The medela you mentioned may be the dual electric plus, which is cheaper then pis. Freestyle is the hand free one, much more ex. Anyway, not many good reviews for freestyle. Your Ameda is the lactaline right? Did you buy the whole set with bag and everything or just the pump set?
@ Nico: if I buy the US set and use a converter to use in Singapore, do you think it is safe? My hb said better not use it this way, but it's much more cheaper than buying in Singapore....
