The XiKAR Crystal 100 humidifier has a special polymer gel that absorbs up to 450 times its weight in fluid. Plus it maintains a perfect 70% humidity. That means better cigar humidification and less work for you. A word of caution, though: USe ONLY XiKAR's own PG solution, or plain distilled water.
Well made with three different mount options. They don t wimp out on the magnetic option. I prefer just laying mine flat in the case. Which you can do by easily removing the other two options. I check mine every four days, which allows me to decide to add distilled water or wait a bit. The design makes it easy to see how the water crystals look and the top of the case makes adding water very easy due to it s random different sized holes on top. This is a great non-electric 100 round Humidifier.
This is my favorite humidifier. Always use the propylene glycol solution and it will keep your cigars fresh and free of mold/mildew for months before a refill if you have a quality humidor. This keeps the humidor at a consistent ~75% RH. It is filled with dry crystals that expand and turn into a solid gel when filled with solution. Never use tap water ever. A+ product! Xikar is the best!
The crystals may have stayed moist for 3 weeks, then dried out. When you shook the container, it sounded like a baby rattle due to the dry crystals. Made an attempt to restore the crystals in a moist condition, but they would only stay this way for a few days. Maybe I received a bad one, but I'm not willing to loose more money by trying this one again. In my 300 count I have a electronic humidfier, with a couple of fans. I wish they would make these for smaller humidors.
Keeps the humidor as stated...70%. Excellent and cheaper substitute for the powered humidifiers. If only everything else would work as easily and well as this.
