I think I've settled on the Source Orb V3 vape. Its major selling point is Quartz Terra atomizers, which are quartz bowls with ceramic donut heaters (above video is of the older all ceramic Terra atomizer). So metal heating elements never directly touch the concentrate. Donwside I read is the Source battery hasn't enough power to get good clouds off the Terra atomizers. I'm new, so it should be OK right now, and it's 510 ego threaded so can swap batteries later.
Anyone have recommendations on cheap no leak e-liquid attachments for 510 eGo batteries? Local or online. The Source Orb V3 is concentrate/wax only.
