I was using the Medela Pump in Style for about a month and grew tired of it. It hurt, it was LOUD, and then I found out that it's not a closed system, meaning that the hoses can build up condensation that can mildew and contaminate the milk I was pumping! Eew! I eventually bought an Avent Isis Duo and love it. The good hing about this pump is that you can use a pumping bra and the containers do not contain BPA. I never got comfortable with the suction levels. I had to replace the faceplate because it kept popping off. Doesn't seem to be designed very well.
