My wineador is holding rock solid at 63% humidity after the past month. Personally, I'd try the wet brick if it didn't take up so much room and worked. So long as the humidification source is safe and works well, I couldn't care less what it is. Just happens that the KL only cost me $9 bucks and I've only used approx 1.33# spread out over 5 small trays. Lots left if the need arises. So far, the wineador is much more stable than any of my wooden humidors were. Extremely pleased with results. Appreciate positive info and advice from everyone.
