I think all the testimonials are fake, if this wasn't clear to everyone. I thought they might be real at first but none of them exist. I actually thought that was kind of shitty to do, since they use real companies and media outlets.

(I don't really follow fonts but I do know there is a subculture crazy about them, so I thought it could be theoretically possible that people would write reviews of them).

I clicked the Fast Company one because the quote seemed most fake to me and it was a real article. I learned that the underlying problem here is that eye charts only have like 10 letters on them, and this font attempts to guess the rest so you have a full alphabet.

You can click them, they link to their sources.
