Product review (4 stars): Exactly what I needed
The temperature seems accurate (it corresponds with the thermostat in the room) and the humidity is very responsive (you could breath on it and see the change...).  I keep it by the baby's crib, and adjust the heat/humidifier accordingly.  The actual accuracy of the relative humidity is irrelevant to me - I just know at what reading this monitor gives where my baby seems comfortable.  Exactly what I needed.
