Product review (5 stars): Easy Peasy to Set Up and Use + It has Magnets for Hanging on Metal Surfaces!
This is a nifty device.  I am challenged by all things that require assembly, but it was easy to get this into working order.  It does need two aaa batteries, which are Not included, so be prepared to add your own batteries.  That said, it was easy to get it running, and the instruction booklet is pretty clear about how to choose between Celsius and Fahrenheit, as well as how to calibrate it.  It did need calibration, but that was easily accomplished as well.  The picture shows it sitting on a stand, and that is one option - the stand is included and works well.  BUT, the even cooler option is to hang it on a metal surfact (without the stand) using the magnets on its back.  I love this option because it doesn't take up space on a table but rather occupies a space which was not otherwise functional.  And it can be hung at eye level, which is another bonus.  I am very pleased with this device that measures interior humidity and temperature.
