Good day, i started vaping 3weeks ago using the rx200s with tfv8 (my first ever setup)and i love it. Before starting i knew i would be a cloud chaser.. I need advice on what setup i can buy that will fit snuggly in my pocket when at work, (basically like a packet of sigs which didnt bother me) as i have to carry around my current setup in my hand... i would like to be able to build my own coils like with the tfv8, and Battery sgould just last at work as i will use my current setup as my main setup (i vape alot more at home than at work) thank you in advance..
