Nothing is really wrong per se with a $700 luxury juice product. And I'm sure the juice is fantastic. But a $700 juicer is like a $700 Swaine Adeney Brigg umbrella. The difference is that Swaine Adeney Brigg realizes that it's a niche vendor for a small market and doesn't raise $120 million to become The Next Big Thing.

A $700 juicer that you could use with your own ingredients would not be a problem (In fact I'm sure there are plenty of $700+ juicers on the market already[0]). A $700 juicer that can only use ingredients from one company (and only if they let you) and that gives you zero control over the content of the juice is a just dumb. If I was the sort of person that considered $700 reasonable for a juicer, I would absolutely also be the sort of person who would want to experiment with different juice ingredients and ratios.
