I agree, Boveda Humipacks are the best for small/medium humidors. They are super easy to use, you unwrap them and throw them in your humidor, they can even touch the cigars directly, it won't hurt them.
They work to either remove or add moisture to stay at exactly their advertised RH.
They feel like pouches with water in them when they are working and turn rigid and will thin out when it's time to replace.
Also do yourself a favor and buy their humidor tune-up kit

And their 72% packs

The tune-up kit will get your humidor seasoned the right way and your hygrometer calibrated. You may think that you are at 66% but in reality you could be 70% or 58%. You really don't know until you calibrate your hygrometer.
Also, ditch the puck humidifier and any other source of humidity as all it will do is fight the Boveda packs.
I know this seems like a lot of work and expense but you will truly find that it's a lot like your Jeep, a little bit of expense and work and you get to enjoy something awesome. Don't take care of it and you will drive/smoke a beater.
Enjoy!
