Thank you for posting this! I haven't a clue about any of it yet. I have just ordered my first starter kit. A couple of questions, if I may; Why do you need to wait 15 minutes after filling with liquid? Is it to allow time for it to seep into wherever it needs to go? Do you need to keep it a certain way (upright) when waiting those 15 minutes. When you are done vaping, do you store it a certain way while not using it? What happens if you don't tilt when filling and spill liquid somewhere it's not meant to be? It looks kinda fiddly but I guess you get used to it. Sorry, that was more than a couple of questions!
