I got mone yesterday and on my first refill of the tank. It is awesome. All I did was blow thru the atty a couple of times, put the empty tank on and gave it a half turn, took it off filled it 3/4 of the way full put it back on (make sure it clicks in). A few puffs and all I can say is OMG. Great th, vapor and taste. I left it laying on it's side on a napkin over night and no leaks. This is awesome to say the least. Your gonna love it
