Wow. Just wow. Why did I not hear of this pump sooner? Comfortable, portable, lightweight, oh- and more than double the milk!! Seriously, it is almost a crime that the insurance companies just give out inferior pumps when this is available. I was concerned when returning to work with my second baby that I would not be able to produce enough milk. With my first, I pumped like 6 times a day at work to make enough with my Medela PISA. Now, those worries are gone. Totally gone!
