The Juicero was terrible hardware in the sense that they could have made a product that was functionally similar but cost far less to make. It seems like they got a hardware engineering team straight out of college and gave them no constraints or budget. You have a giant CNC'd aluminum frame, a custom gearbox, a custom power supply, a custom drive motor, etc. All of this is only necessary because they decided to squeeze the juice out of the bags by applying thousands of pounds of force to the entire surface of the bag at once vs. using a roller or something. They were likely losing hundreds of dollars per unit even when they were selling the press for $600.
Squeezing the entire bag was the selling point. It's not negotiable. The important question is how much money they could have saved without changing that aspect.
