Invest in a pump with features that are better customized. This pump does not achieve maximum milk flow.*Update* after a little over a week of using this pump twice per day it has totally konked out. The suction stopped working. I will contact Playtex and see what they can do about it.*Update* Playtex is sending me new tubing and another motor. This seems to be a common problem with this pump. Save your money and purchace another pump. I would change my rating to one star if I could.
