I took my resevoir apart, took out the foam and replaced with the beads!
Works like a champ in conjunction with the rest of the beads!
What type of barrier did you use to keep the beads from blasting out?
I have just the Cigar Oasis XL and replaced the foam in mine with expanding polymer crystals. (They look like the stuff in the humi jars that expand when wet)
I have been very happy with this setup other than the fact that I noticed some small specks of mold on the crystals the other day. I took care of it, but thought it might be a good idea to switch to beads if I can get it to work.
I love the CO. The hygro is way off, but once I got it dialed in with my digital (and tested) hygros, the humidity stays exactly where it is supposed to and the cartridge with the crystals in it has lasted for months without recharging.
