Product review (2 stars): Very inaccurate indoor and outdoor humidity readings. Reading significantly lower than actual humidity!
The temperature appears to be reasonably accurate however the Humidity reading were 8% low on the outdoor reading and 5% low on the indoor unit. Putting the outdoor sending unit right next to the indoor unit inside the house the readings should be the same. They weren't! The temperature reading was close (within 2 degrees) the humidity readings were different??????? I then brought a known to be accurate humidity gauge in and set it right next to this indoor and outdoor unit side by side on the kitchen table. Both the indoor humidity reading as well as the outdoor reading showed a much less humidity reading than what the humidity really was as well as showing both readings different than each other. Here is Arkansas where humidity is an issue showing a much less humidity reading than what the humidity is could cause mold and mildew problems. I cannot recommend anyone buying this unit!
