Xikar Crystal Clear Jar 4 Oz.

I purchased this item because it stated it would Always maintain 70% humidity. It will not go above 65% in the dry winter air. I contacted Xikar customer support and they said it is working correctly due to the dry winter air, and no product would go above 65%. I have had other products that provided 70% in the winter. All of their literature says 70% is the best and that this product will do that, but that is obviously not true, regardless of how much solution you add.
