Negative Positive
Title: Inaccurate
Review: I have 2 other hygrometers, 1 is on a dehumidifier and another digital one. Both of the other hygrometers agree on the humidity, and disagree with this one. Even if I adjust the set screw so that the current humidity is accurate, it does not adjust properly when the humidity changes. It regularly says that the humidity is 10 - 20 percent higher than it really is.
Is the review positive or negative?
