overall nothing wrong with the refurbished but check calibration as mine was off by 5%. and if you have a tall cabinet humidor the fan is not strong enough to get humidity up to the top of it so i placed mine on the top shelf instead and it works fine.
While this humidification system works excellent, in a larger humidor, where you would like the humidity to be even through-out, the humidity levels are read too close to the device. This leaves a void of correct readings of humidity levels on the opposite end of the humidor. As a improvement, if there was a sensor that can be plugged into the device and positioned far away from it, the device would stay on until the levels of humidity reached that point. to compensate this this deficiency, raising the device’s humidity indicator to the maximum is at 80%.
Still not enough to stay on. It will read the levels right in front of itself and turn off.
