Can we talk about how wrong most paint thickness gauges are?

I tested 4 different budget gauges against a $600 Elcometer at a shop in Denver last Tuesday and the cheap ones were off by up to 30 microns on bare metal. Makes me wonder how many re-dos happen because people trust those $50 Amazon specials. Anybody got a gauge under $200 that actually reads consistently?

Bought a $50 gauge off Amazon and it told me my primer was somehow thicker than the paint itself. Took it to a buddy's shop and he laughed so hard he offered to calibrate it for me as a joke. Now I just stick to using the same cheap gauge every time so at least my measurements are consistently wrong.

Used to think expensive gauges always meant accuracy, but your story totally flipped that around for me.
