Product review (5 stars): The fun is selecting where to locate the outside sensor
It is everything I was hoping it would be. Readings are accurate and checks with weather data available on smartphone.. The temperature and humidity readings are right on.

The fun is selecting where to locate the outside sensor. Outside...yes...but somewhat shielded from harsh weather is a good idea. It can always be moved which is great. Blinking red light on the sensor reassures that the sensor is operating nice feature. It's 4 degrees outside right now, not good news but it's accurate!!!
