Product review (1 stars): Disappointed
Just like the other reviews. Purchased the pair and after 24 hours side by side the temp difference displayed was off 7 degrees! Humidity however was only a couple % difference. Sitting next to another different brand combo unit the temp was close to one but the humidity was a consonant 10% difference. So I have no idea what the humidity is.  I was under the impression that these were going to close in accuracy.
