Seems accurate, looks nice, provides lots of information. Screen lighting is great for dark locations but to save battery power it turns off quickly. It comes with one outdoor sensor but you can add two more if you want to monitor the temperature in three places plus indoors. For example, you could have one in the basement, one in the garage, and one in the attic. This is a really neat feature that is not really promoted in the description.
