Product review (3 stars): Humidity reading stopped updating
I used this inside a dry box for my printer filament. Once I placed it in the box with a lot of desiccant the humidity reading got down to 10%. However, it stayed there for weeks. I figured the box was well sealed but had my doubts. I took it out and just placed it on my desk and it remained 10%...for hours. Temp seems to update fine though.
