It's me, Bebe, the newbie. Got my Provari mini today and have been playing with it all day. I LOVE it! And I'm glad I didn't waste my time with other mods/kits. Quality thru and thru! I ordered 2 packs of cartomizers, 1 pack is DOA. I had read that somewhere else, that someone had the same thing. But it's the Protank that is giving me fits! When I seat the atomizer head, it doesn't touch the top assembly after the bottom cap is threaded on the tank. Then, when I attach the tank to the Provari, knowing I'm not supposed to tighten it too much, it gives me an open error. So if I tighten it down all the way, it finally makes a circuit, but the bottom thread of the tank is way too tight on the Provari unit. I played with it for quite a bit, surprised there wasn't a troubleshooting tip on the provape site. So my big question is...should I spring for the Z-atty? Would that work better? Rebuilding coils and wicking is up my alley, no problem there. Both atomizer heads that came with the Protank both give me the same problem. I ordered their replacement head 5 pack, though they charged me, they forgot to include it. Need some input from you veteran techs or Provariantis out there, your help is greatly appreciated! One other question , it doesn't appear possible to drip with the Protank? Or can I? If I need a different atomizer to drip with, someone please tell me where they get them for the Provari. One other comment, the Provari batteries all arrived almost fully charged!
