Negative Positive
Title: Not very accurate
Review: I purchased three of these hygrometers to use with three different dehumidifiers in different rooms of my house. Immediately after receiving them, I performed the salt test on each to determine their accuracy. One was spot on, one a little high, and the other a little low. That was a bit discouraging, but since they didn't cost much, I kept didn't return the inaccurate ones. After about a year of use, two of them suddenly became highly dysfunctional, giving wildly inaccurate readings, making them essentially useless.I would not buy this brand of hygrometer again.
