The Humipuck is heartfelt beads, along with a sponge to make it a lot more user friendly. You just wet the sponge and go...no messing around with loose beads or tubes.

I still prefer the loose beads, but for my application I would probably need a dozen humi-pucks. I will probably still buy one for my desktop though. Both Mark with cigarmony.com and Mike? (I think) with heartfeltindustries.com will treat you right.
