(From husband Gary) I have always used some type of "solution" for my humidor. I have read many reviews on here about "just save your money and use distilled water". Folks, I am not a chemist, but obviously there is a reason why they make this stuff. I think Xikar produces wonderful products; I use this solution in the Xikar Humistore that I also purchased on Revain. Together, my humidor stays at a perfect 70 percent. I consider it a small price to pay to protect an investment. Not only your humidor, but also the sticks inside. I have not had any issues thus far. What I will say is that these products replaced the original sponge credo that came with the box, and it was difficult- no, actually impossible to get the humidor to 60%. This product as well as the Humistore has eliminated my humidity issues! I will also say that there are other products/ solutions that may accomplish the same thing, but I am happy with the Xikar solution.
