Product review (5 stars): Excellent
I really like this item. The display is very large and accurate. Both the temperature and humidity readings work great. I needed it keep track of the temperature in my porch which is only partially heated during the Winter months and has large plants inside. It takes just one AAA battery which I recharge every few weeks. You just press a button on the rear to switch from Fahrenheit to Celsius. I haven't figured out how to set the clock yet but the time is not needed by me.
