Any style product like this will give you similar results. If its not a 2 way solution then the best way to look at them is just a way to add humidity over time. They are also highly effected by temperature. Throw two of these jars in a full cooler with cigars and they are solid. I think people over complicate humidity. Over time you will get used to your setup and will be able to just know if things are too high or too low. Like a cook who does not measure anything but makes great dishes everytime Thanks for sharing your experience.
