Title: Works great, when it works
Review: When you can get this very tempermental pump to work, it works great. But I have had the same problem that others have reported; the little membrane/valve thing keeps popping off, thus causing the pump to lose all suction. I have to stop pumping and fish the thing out every 2-3 minutes. I can get just as much milk with this pump as I can with my Medela Pump in Style Advanced, but I don't like having to stop and unscrew it every few minutes. And according to the reviews, I am not the only one with this problem.
