Product review (1 stars): Inaccurate readings
It reads about 10 degrees below the actual humidity level. So it is relatively inaccurate of humidity, and roughly 3 degrees inaccurate of the temperature. Mine read 50% humidity when in actuality it is 60-65%, and reads 68 degrees farenheight when it is actually 72 degrees. Not particularly happy, especially since there is no way to calibrate this device. You get what you pay for.
