I'm obviously slanted, but just wanted to say that I have a humidor that has a puckifier built right into the lid and it worked great while I used it. It's a super cool invention and it's nice that you can velcro it right to the lid in your humi. They're versatile.
When the beads in the puckifier wore out and got crumbly and stinky, I just went with soft beadsticks. They're still going strong.
