A meal replacement beverage.
The ~2023-05-01 cocoa version is not good enough.
The 2019-07-26 cocoa version is like drinking chocolate ice cream, including the gummy mouth feel afterwards. It's definitely only a "treat" and not a meal replacement.
The 2019-07-26 vanilla has a definite flavor but is definitely tame. It also suffers from the mouth feel problem, which I think would be a problem for narration and singing.
See Soylent for a lot of notes which also apply to this product.
