Product review (4 stars): The indoor unit is sturdy with an easy to read display
The indoor unit is sturdy with an easy to read display. The accuracy of the outdoor temperature will be largely influenced by the location of the sensor and whether or not it gets direct sunlight. I have tested it with 2 other thermometers of different brands that I own (I like to keep them in different areas of the house..) and the temperatures only varied by around +/- 1 degree at the most.

I found the indoor thermometer to be much larger than anticipated at around 3.5" wide and 6" tall. It was not really an issue for me but most other thermometers that I owned were a few inches shorter.
