Kaiser supplied pump?

So I wanted to see if anyone else has Kaiser insurance? In the states or just California. They will supply a free Ameda purley yours breast pump. I've read really bad reviews about them. Anyone used this pump before? Or if you have Kaiser and they offered you this pump, did you go with it or did you pay the difference for a different pump? Which I know is an option. If you did that, what pump did you get and how much did it cost you? Thanks ladies!
