I have the Pax 3, don't rate it to highly. My go to vape for the past while has been the mighty from Storz and Bickel. Very reliable, excellent battery, holds a reasonable amount, smooth with little draw resistance. The crafty seems great if you want something more low profile for out and about. Heats up quick, gets you baked pronto if that's what you desire. I like the sound of the hybrid volcano but might have to wait till Christmas with that price tag. Link below for the Crafty if you want to check it out, the Plenty sounds good too but not very discreet.
