Triebwerk Here!

Damn, that concept art looks way better than the actual fans...

I can imagine that they'll do well anyway, though. The Monsta radiator, which is incredibly overpriced, seems to have done well enough.
Plus, there seems to be quite a large customer base that will buy things that are extremely expensive, because they are extremely expensive. This is the business model that german manufacturer Innovatek has been running on for ages. They produce junk and sell it at enormously high prices. Their customers are convinced that Innovatek-stuff is the best there is...

Feser could have the same kind of effect. Since their products aren't nearly as horrible as the Innovatek ones, they might do very well indeed with this business model.

(E: See commitment bias/escalation of commitment on why this kind of thing works)
