luvin colton (701.4 days ago) hygeia sp? enjoye , it can safely be transferred from mom to mom for easy sale or for a friend to go in on together like the hospital pumps, medela is not safe to resell. i love the way it works compared to medela , you can pump one or both sides, and you can easily record your baby crying or cooing and playback when its time to pump. it comes with nice size shells that are perfect for average or bigger nipples. i got mine brand new for 175.00 usd
