Xikar DryMistat - Crystal Tube Humidifier - 25 Cigar Capacity

Now this really is genius! No fiddling, no fuss, no distilled water - just fill it straight from the tap - it even shows you when it needs refilling. Works quickly and efficiently and you can leave it right next to your cigars. It will not damage them. Highly recommended item. Little tip, if you have a small (x4 cigar) travel humidor, such as the Vector Travel Humidor that I bought from C. Gars Ltd., just remove about half of the dried crystals before first use or only fill to 1/3rd with tap water, otherwise it works too well and zaps a small travel humidor up to 90% humidity which of course is useless!

Just bought this humidifier tube. its easy to use, clean with no fuss, and bother. Just topped mine up as per the instructions, lefted it for 10 minutes and popped it into the humidor, job done.
