Has anyone had this long enough to know if the battery will last at least one year?

I've had mine for over a year and it's still going... I've had other battery powered products from a seller and the batteries lasted only a few weeks... It's because the batteries have been installed in that device since the assembly line...If by chance they don't put the little plastic strip between the negative side and the device, the batteries will go bad...

Any way to calibrate temperature?

Calibrate means that you adjust your measuring tool (e.g. thermometer, hygrometer, speedometer, etc.) to give a known value when it's measuring (detecting) that value; you usually do this by adjusting a screw or other mechanism that results in the unit showing a 'reading', or measurement, of that known value on its display or output. This unit does NOT have any calibration adjustment.

What do the low and high represent...is it for the last 24 hours?

As several others have said, it's the HIGH & LOW since it was reset. To reset, HOLD the button marked F/C until it resets. Each time that button is pressed, the displayed temperature changes between Fahrenheit and Celsius.

In China. I bought 3 of them, but don't find them useful. The setting for humid, dry, comfort is inaccurate for a relativity level reading in a home environment. At least in the Midwest region. They say 49% is dry when in fact it's too much for a home to carry, at least in the winter colder temps.
