Query: Easy to use, low maintenance humidor solution.

Threw one in my new (unseasoned) desktop humidor not expecting much. Low and behold after 48 hours the humidor stayed consistent at 70%. Mine came filled to the top line and I haven't had to refill it since. But when I do it's a 1 minute job. Much better than the messy and unreliably puck-style humidifiers. One tube/25 cigars seems to be the right ratio.
