You had me at "silica hybrid"!
SS mesh and ceramic is cool, but I've been a silica junky recently.

I just watched Scott's review. I'd love to find a seperate rba that sets up like this without it being attached to a device. I'm not interested in trying to twist together R-NR-R wire like the penny or oddy. this build looks super easy but I don't want a hybrid.
