I just got my 510 manual this morning, charged it for 4 hours. I'm getting some vapor, but nothing like the big clouds I've seen on youtube and I don't feel anything on my throat. Tastes kinda flowery. The atomizers feels warm/hot. I ordered marbelo high cartridges but no juice ( Iusually smoke marlboro reds). How do I know if it's working/ what am I doing wrong? It is very dry hear right now (about 8% humidity)- is that why I don't see clouds of vapor?
