Title: Very frustrating
Review: I have found this pump very frustrating! When I try to use it, I end up having to take it apart about 20 times trying to pump 4 ounces. The small round plastic piece pops out so many times that it makes it an epic task to get 4 oz of breast milk pumped. I'll have to try an electric, or another brand of manual. This is driving me insane.
