Medela Pump In Style Advanced On-the-Go Tote. Acquired in 2010 and made use of daily for each of my children's first year of life.

　　Great pump in excellent working order. Brand-new power adapter bought in 2013. All other parts are initial. I have 8 collection bottles and 2 sets of guards along with the cooler bag and ice bag.

　　Included is a battery pack & vehicle lighter adapter so you can pump anywhere, anytime.
