Negative Positive
Title: waste of money and time
Review: Couldn't figure out why my cigars were dry and burning inconsistently. I calibrated the hygrometer with a Humidipak, then used it. Thought everything was fine. Sure enough, after a month or so I re-calibrated to find out it was way off. No biggie, I thought it was about time. Now a couple months later I re-calibrate again. Five days ago, the calibration was perfect. Interestingly, the % kept rising each day. I checked the calibration and it's again about 10 points off. This isn't worth the time or money to risk a good batch of cigars.
