Hello you are right about the difference I have had this humidor going on three years, summer months no problem, but winter terrible. I will store the humidifier on its back, (instead of the holder that comes with the Humidor),laying on top a few cigars, (I have left the wrappers on), in the bottom and then re-arrange the cigars in the top lift out to tray to keep several of the slots in the shelf un-obstructed this seem to help.
