Product review (5 stars): Can't live without it now!
My husband was apprehensive about it at first but we can't live without it! We loved it so much we ordered two more. With a newborn and an old house we like knowing the temperature and humidity levels of each room. We use it each and every single day and how one is just about every room. They are pretty accurate although sometimes the humidity is off by (+/-) 1 percent.
