in my experience be careful with humidity devices in travel humidors, with my 10 count I thought it would be important to use the small included humidity insert (one of the longer fits into one of the cigar slot kinds and the humidity jumped up quickly (about a day) in the air tight container. If it is going to be sealed most of the time I would think a device to get the humidity about where it should be and then remove it, before adding the cigars allowing the cigars to regulate themselves.
