Humidor beads-Anyone understand the science?

[forgop]

I'm looking to buy about 3 lbs now and trying to distinguish what is different between the beads sold from Heartfelt, Shilala, Cheap Humidors, etc, etc. Is there a logical explanation that distinguishes one as being better than another? Trying to justify that much money on beads or buying another Cigar Oasis at that price.

I am at work and too busy yo search right now, Duane, but this has been discussed ad nauseum here if you do a little digging. :)

I know nothing about the science. Only that the Heartfelt/Cigarmony beads are silica based and work perfectly for 4 years. Others like Shilala's HCM(Clay based) beads just as well. :2

I decided what the hell and opted for 4 lbs of RH Beads from Cigarmony. I like them being in the tubes rather than the bags.
