I have a 30-count Esplenade humidor, with a glass-window top. The bin is only 2 1/4" high. It came with a thin long squared humidifier (like a square cigar) that is supposed to be velcro'd to the top of the lid (not onto the glass, of course). When I did attach it the weight of the distilled water promptly caused the humidifier to fall to the bottom of the bin, actually coming apart, with part of it still velro'd to the lid.
I had to put the humidifier back together and just lay it on the bottom of the bin at the front of the humidor. It has actually done a decent job keeping the rH at 65% (the seal on this humidor is dynamite, unlike the large Arch Barrel I also have).
A Gel Jar is almost 2" high, and I don't know if having the top so close to the lid will affect the performance (probably not, but I *am* a compulsive paranoid ^_^ ).
Are there any higher quality humidifiers that are made for these smaller humidors? What *is* nice about the one that came with the Esplenade is that being shaped as it is, about a 1/2" wide, it does not affect filling the humidor to capacity, as the bin is 6 3/4" front to back, and I can still line up 6" sticks right up to the humidifier.
Any help, including "if it ain't broke, don't fix it," is appreciated.
