@FamilyBiker Dripper like air flow? They're nice, maybe a little low on juice volume, tighter than I'd personally like for air flow, and made almost entirely of glass so dropping it is always a concern, but nice I had one for a few days, it worked well and had good flavour, never leaked on me either. Building it was simple enough but little room for anything exciting coil wise. Not much similar to chose from.. billow v2 nano maybe.
