Thanks so much everyone.
I've been looking for a upgraded tank and not sure which to get.
I don't like the tank that came with it, it doesn't sit flush, the port for adding juice can leak and could be wider. I had to replace the stock coil for spitting really bad with a baby beast coil.
I'm not a fan not of clouds or looks, I just want to replace smoking cigs and have a nice taste.
What would be the best tank upgrade for me? I like to diy stuff so maybe I should go RDA... ? Not sure yet still learning about it.
