I think you and the parent comment are both partially right - from having watched a number of teardowns, the Juicero was (if anything) massively over-engineered in terms of number of parts, cost of those parts, how they were machined, etc.

It was also kind of clear that it went too far, that a more experienced hardware design and engineering team would have found (not a cheaper), but a more effective way to handle those same challenges.

What you mean to say is that the Juicero was overbuilt and underengineered. As the saying goes, "anyone can build a bridge, it takes an engineer to barely build it".

This reminds me all too much of Coffee Equipment Company which back around 2005 built the world's greatest coffee machine, Clover. Unfortunately, at $11k per machine even Starbucks, after buying the company, wasn't able to find a profitable niche for it. Clover machines were, are, beautiful machines that are able to repeatedly and dependably turn out genuinely great cup after great caffeinated cup; the problem is that it was a solution in search of a problem, much like Jucero.
