PLAYTEX DOUBLE ELECTRIC: We were trying to be frugal so we got the cheapest double electric at the store - the Playtex Double Electric. I was accidentally transferred to a lactation specialist last week on a call about a different question (tell me things don't happen for a reason!) who told me that the Playtex pump was not one that is made for daily pumping. Also, it is an atrocity to hold, I was getting really bad pains in my hands from pumping daily (probably working my way toward arthritis!). Also, the tunnels are straight instead of angled downward so you have to sit hunched forward the whole time!
AMEDA DOUBLE ELECTRIC: so I ended up getting an Ameda Double Electric pump because it looked easier to hold - it is! And it's lighter than the Playtex so my hands feel much better. And the parts are so much easier to clean (for someone without a dishwasher).
The only problem I'm having (and I just got it two days ago) is that this pump has little diaphragms that are a necessary part of the suction feature and my cram up and I have to constantly release the cap so it will pop back into shape. I really think this is a flaw because suction greatly decreases when it gets all crammed up. Ameda claims their diaphragm feature is great because it keeps air from getting into the bottle while pumping, which contaminates the milk. So then how does it help that I have to keep opening it to make the darn thing operate correctly?!! I do plan to contact someone regarding the issue.
Honestly, I say go on YouTube and research the pumps you're most considering and look for what seems to be easier to hold, easier to clean, etc. To be honest, in my own opinion, I say that COMFORT is the number one priority when it comes to pumps! Because if you're uncomfortable then you end up unmotivated to pump, which was my case with the Playtex. The Ameda is far more comfortable - makes pumping so much easier on me in every way compared to the Playtex.
Also, as my lactation lady said: make sure you look for something that is made for daily use.
