Pros: closed system, strength/speed control, milk can sit in the bottle holders, nice bag
Cons: none that I can think of
I had this pump, and loved it. It is a closed system, so milk can not get into the tubing/or motor. You can adjust the speed and strength on 2 different dials. It has a bottle holder on top of the pump, which is very convenient when you are trying to pump with top heavy bottles (because the flange is on) and you need to set them down for a min. I also have a medela pump in style, and would recommend this pump over the medela. It also comes with a car jack, so you can pump in the car...which I love because we camp and travel!
