I can't compare them to other pumps but I have a manual Avent & an electric one... and I got more from the electric but that could have been cause I didn't get a sore hand from pumping lol

I like the fact that it has the soft "petals" that "massage" your breast as it pumps. It's a shame you not near me or I'd say you can try it out if you like... I'm planning on selling it as I haven't used it for 4 weeks and I can't seem to find the time to build up a supply for the freezer
