I would have done a bit more research and found the extra cash to go straight to a tube mod and sidestepped pre-filled carts and tanks, I'd have avoided USB batteries with their own feeble built in buttons and everything 'auto'...
Easy to say now but as a noob VV, VW ohms watts and lists like 18650, 18350 etc makes your head spin.
There in a nutshell is the value of this site as you can get real world advise from real users and not a biased sales pitch from a seller trying to shift something with a good margin or gathering dust on a shelf.
Other than that I'd have done it much sooner and not wasted any time sticking itchy plastic to my ...., chewing something that gave me dog breath or taking pills (Champix) that were nothing short of trippy and would probably sell well on certain street corners !!
