Title: Calibrated perfectly, right out of the box...
Review: I purchased this and the Boveda calibration kit. After letting the hygrometer sit in the kits air-tight bag with the humidipak for a day and a half, I found it to be perfectly calibrated. No complaints and will probably buy a second for my smaller humidor.FYI - You can reuse the Boveda calibration kit for up to 6 months after you open it according to the instructions. I didn't know that at first and thought it was worth sharing.
