Review on Precise Humidity Control With Xikar PuroTemp Round Digital Hygrometer, 10-Second Refresh Rate by Bradley Mutha

Works as expected, I bought a boveda calibration pack just to see how accurate it was, because it says 2% +/- accuracy. It was spot on. Just to note this comes pre calibrated and does not allow you to calibrate it. I would recommend this to anyone with a humidor, takes the guess work out of reading an analog hygrometer and trying to determine which side of the line its on. I have a glass top humidor so it is easy just to glance at it quickly without having to open up my humidor.After I had purchased this online I noticed that my local cigar shop(Binnys) had it cheaper than on here. So ask your local shop before buying.
