Product review (3 stars): May not buy it again
I bought two of this item. After receiving them, I put them on my desk to see how they both work. These two unites have never showed the same temperature or humidity at the same room and the same time. It was up to 4 degree difference on the high or low temperature section, 2 degree difference on the indoor temperature, and about 2%difference on humidity. Now the indoor humidity is 27% and 25%, the indication of humidity level is high on both unite.
If you care about the accuracy, you probably don't want to buy it.
