OP, thanks so much for posting! It was very helpful! I also got the Spectra S1 with no upgrade fee in 2018. And they were surprisingly fast in responding and shipping.
11:28, I’m not the expert in breast pumps, but I can tell you what I’ve heard from asking around. Most people recommended either the Spectra or Medela. I talked to someone who had used both with different kids, and she said she definitely recommended the Spectra over the Medela. The Spectra S1 is like the S2, but has the added option of being able to be battery-charged, in addition to plugging in, in case you need it on the go. She said that that can be helpful for traveling.
