Ameda Elite

The positives about this pump is that it is easy to assemble. It's very quiet even at the highest suction setting.
However it barely takes any milk out. There are two knobs to self regulate the rhythm and the suction. It could partly be due to my incapability to tune the two settings, it can take me up to one hour to express 100ml. Also the rigid flange does not feel right on my breast. When I express with another pump (with a soft flange and two cycles settings) it takes me only 15 minutes to express the same amount of milk.

I have never had great let down with this machine, and I find it doesn't help me build up my milk supply as well as other breast pumps. Also I have to think too much while expressing about what speed or strength it is on.
You don't need to do any work, plus it is easy to set up or pull apart quickly.
This pump is quite uncomfortable, I don't like the way it feels, and it is very hard to get a let down. It is also hard to get the perfect speed or strength. I also find that it takes up way too much room on a coffee table.
