Viper is a great guy with great products. You can email him anytime with a question and he will be happy to answer you. If you are unsure of how much you would need for a particular humidor, he is happy to help with that as well. Using the beads will make it much easier to maintain your humidor.
I had used them for quite a while prior to getting my cabinet humidor which has an electronic humidification system in it. Even with this, I plan on getting some beads as a backup system. With the frequent power outages here during hurricane season I don't want to be left hanging. No Power = No Humidification :wink:
