I use this hygro thermometer only for our cigar humidor and am thrilled. It differs only 2% on my Spiralhygromter and this value enough for me, because I want to stay between 69-72% but not fall below values of 65 and would not exceed more than 75 values. The room temperatures I have also compared the weather station, the more precisely 1 degree from enough for my purposes as well! What I really like is that you do not have to wait forever until you know what humidity prevails, when I open the Humi listed the unit equal to loss of moisture, if I shut him he has in about 10 minutes back to the actual value in Humi , Also convenient is that the part is not larger than a matchbox, only it is slightly higher fits perfectly pure and makes even what her. I can not say anything, I'll add in due course here an update on the battery life.
Price / performance is also great, all other hygrometer with good rating were more expensive so far I can only 5 stars for these little helpers give!
Update: I bought a second one for another Humidor Hygro and note that both display the same values - after about 15-20 minutes, the values have leveled off! Bin after about 6 months is still very satisfied!
