I posted a couple of other times here the past couple of days. Came across this forum while looking to buy a TFv4 tank. Not really new to vaping as I've been on and off quitting smoking the past year. So I can tell you that disposable ecigs was a complete failure towards the beginning of the year. Went back to smoking until around the beginning June where I used a vape pen. That worked for about 3 weeks until the College World Series where having a good time out and about that pen was not good enough. So about 6 weeks ago after doing like literally a month of research I bought a Sigelei 150W mod with a Herkales Sense tank. This thing is a beast and yes I have tested going out with not wanting to smoke. Overall I'm glad I did the research and wish I had done it sooner!
