Anyone have alcohol measurement devices?

I feel like these mystical devices cost absurdly much to get a bare minimum of accuracy, and then you need yearly calibrations. like what. I drink way too much, I know that. I would just love to know exactly *how much* but it’s so expensive! Sucks. The cheapest barely trustable breathalyzers would run over 130 euro here in Finland… But I would love to hear y’all experiences!
