Product review (4 stars): Nice & Useful for humidity & temperature readings.
Humidity percentages dominate -- with a room's temperature available simultaneously in the background.

We bought it to check out a humidifier -- which, alas, was returned for developing a loud rattle (not conducive to sleep).

Like others, being able to read this in the dark would have been nice.  If you need to, leave a small flashlight nearby for that purpose.

Goes easily room to room.  Stands well on its own.
