I always assumed you use your equipment for business, but now I'm not sure anymore. Don't tell me it's just a hobby?

I do not do any business, it's mostly just something to post about on my non-profit educational website, for another lost souls like me.
You can find hundeds of reviews of some 50$ alibaba DMM or even some reviews of 250$ Brymen DMMs, but seeing what's inside if 70k$ 7.5-digit calibrator - close to non-existing.
So I'm trying to correct that unfair situation myself.
