With all of the free insulated bags the hospital gave us, I'm so glad I didn't spend the extra money on the carrying totes. So far the pump works great. I only gave it four stars because I'm not sure if the dual pumping works evenly. One bottle always seems to fill slow. However, I haven't used it enough to decided if its me or the pump. Also, its a little louder than I expected. However, this is my first pump so I don't have anything to compair it to. I love the adjustable suction, but which I could go even faster with the cycles. My baby is a all buisness eater, so he goes fast. However, so far, pumping goes pretty fast.
