I just bought a new knock off tower vapor (made in china no warranty no instructions) to see what it's about. I've seen people talking about loading it by sucking it up.? Also, how much do you normally use? How long does it need to warm up without product then with? It feels weird knowing if you are getting anything when you can barely taste it. What is the best way to do your breath? How many times can you re-vape? I was excited but I've been having hell for the last 2 days. I'm saving to get a nice one. Thanks for the help!
