No digital hygrometer will be spot on accurate according to what I've read. And they have a limited life.

The $9 one I listed will be effectively the same "good enough" accuracy. RH +/- 5% isn't a huge swing unless you are doing science. Humidors are best at 60-70%, it's not critical, so the company making such a thing doesn't need scientific accuracy.
