Doesn't work. A waste of time, energy and money.
I got this pump through insurance which voids their money back guarantee... Now I'm stuck with a worthless pump and no way to pump at work. I've called way too much and have been sent so many parts, but the simple fact is that this pump has a poor design and does not work consistently. I sit for hours taking it apart and putting back together. After many conversations with customer service and supervisors, they say there is nothing they can do since I got it through insurance. It's loud, has too many components and doesnt do what it's intended to do. Don't waste your time with this pump.
