Query: Better than Medela

I bought the expensive electric Medela Pump in style and used it for 5 months. This is BETTER. Its much cheaper! Its quieter; it doesn't hurt. It works faster! This is portable... I could go on and on.The instructions say that you can hold the suction and milk will continue to be expressed - instead of pumping continuously (which is what the electric pumps do.) That process works - which means less motion and less strain on your breast tissue. This is a really great product.This also comes with 2 of most plastic pieces - 3 of the little 'white valves'. So, if a piece wears out, you have a replacement.
