It Doesn't Have the Power of a Regular Breast Pump
There's a learning curve to it.  It's not as simple as a manual pump or a normal electric one.  It isn't very easy to figure out how to take it apart for cleaning and pouring milk.  The suction also isn't as great as a manual or electric pump, kind of hard to place on the nipple correctly.  The idea of it is excellent since it is hands-free and allows you to move around and do things, but it also leaks easily if you lean forward too much trying to pick something up like toys or laundry on the floor.  I would rather use a manual or electric pump instead.
