I bought this breastpump after reading reviews that it was the best manual pump there is. Now I think I'm going to throw this thing out the window!! I've never tried another manual pump so I can't compare, but I can tell you this one is very frustrating to use..It loses suction all the time, especially with the petal thing. It's very messy as well--I've spilled milk on myself numerous times. I've also sat pumping for an hour and gotten only drops. (And my milk supply is good.) If this is the best manual pump out there, God save us all. I'm getting an electric one tomorrow.
