I love this pump!
I purchased this pump after having tried the Medela Symphony in the hospital after giving birth, and then the Tommee Tippee Closer to Nature electric pump (not a fan) at home. I had many issues with my milk supply and discussed with my lactation consultant the need to pump daily or more to help increase my supply (as a first line measure) and she suggested I hire the Medela Symphony again through the hospital. As I wanted to have a pump at home for the full 6 months of breast feeding I decided to purchase a Medela Electric Swing, I was ecstatic to be able to purchase it for $229 instead of the usual $299 at my local baby store, though I still would have purchased it at $299.
So, the reservoir and attachments are easy to clean, easy to see your milk flowing through and the standard size cup fit me well, so didn't cost me anything extra to get a bigger or smaller cup.
The 6 different intensity settings and let down setting allow me to pump at the highest intensity so I can get the milk out faster, without too much discomfort, and I can lower the setting if it gets too much.
Compared to the symphony this pump is quite noisy, but compared to the Tommee Tippee I had used before it is very quiet. Placed under a cushion I can barely hear it, and it doesn't disturb my son if he is sleeping during the day when I am using it (I don't pump at night).
It's only downfall is that it can only do one breast at a time. I would give it full marks if it could do both as the same time!
