A must have!
This is a wonderful pump.  When used correctly (that means you don't keep your hand constantly pumping, you pump and hold because the suction continues to pump out the milk for several seconds) it is very fast, easy, and quiet.  I could pump with my sleeping newborn right next to me and it didn't wake him up.  I could also get up and walk to another room easily while using it because it was so small compared to an electric or battery type pump.  I loved that I could pump right into the bags and then either store them or just stick a nipple on it and give it to my baby.  Once I learned how to assemble it, it was easy to do so for cleaning.  I will stress again that when used correctly it really was just as fast and better than an electric pump.
