Product review (2 stars): Acceptably inaccurate temperature, wildly inaccurate humidity reading.
Temperature seems to be within 1 degree F of an existing hygrometer / thermometer combo I have.
However, the hygrometer reading is unusable.
In one location, my existing hygrometer reads 50%, the Everspring reads 45%.
In another location, my existing hygrometer reads 45%, the Everspring read 46%, so the results aren't even correctable by scaling and offsetting the results.

Appears to be a sturdy and well made unit, but not useful to me if the hygrometer can't be counted upon. Will be returning.
