This has been driving me crazy in regards to finding an answer! I thought it would be a somewhat simple question but finding an answer has proved otherwise. So here we go, I just want to know the name of the following set ups https://goo.gl/images/AEmdiI https://goo.gl/images/O3dmYC If the links don't work I want to know the name of the "tank" with the rebuildable coil that you wick cotton through yourself and also the name of the "tank" with the prebuilt coils like uwell crown 2 "setup" compared to a smok trvf4 rbta "setup" that you build yourself. Thanks for any help!!
