That's mostly carrot (+lemon and orange) but still it's very dry. See also AvE's video[1] where he opens a bag and its full of processed but still largely intact pomegranate. You can squeeze most of a first glass out by hand[2] but that's about it. To get the rest out a press really is necessary- but Juicero isn't just a press. It's massive machined aluminum billets and expensive gears and a custom motor. The huge aluminum parts are likely the biggest cost sink- hundreds of dollars, easily. If they had made the things out of extrusions they could have saved 80%+ on the cost. Just goofy all around.

edit: also this... enthusiastic gentleman, who is pretty enthusiastic about the contents of the bag[3]
