Here I push the button and then pause for a second or so to allow the ejuice to start heating in order to convert to vapor before taking each puff. You'll find that the coils won't flood as easy where you start hearing the gurgling sound. Drawing on it first often results in saturation.
Now for a variety of flavors I invested the Tumblers with multiple color tanks to catagorize each color like Menthol or Mint flavors in the green, Berry, fruit punch, tropical blends, in the red or violet, tobacco with blueberry in blue, caramel, butterscotch, etc. candy type flavors in amber/yellow tanks, and for others like Chocolate, Mocha, Coffee in the dark smoke color tanks while the clear tanks are reserved for sampling a little of one with another or some new flavor being tried out for the first time while even those may end up in a color tank.
That requires multiple tanks on more then one battery or apv, mod in order to have several set up at the same time. Just to get an idea of what I mean by having a variety of things I took a fast photo of the two mod stands and a couple of other items of interest with the case in front given to someone to try vaping out before getting hooked on any regular smoking habit and another ecig that actually could be mistaken for something else!
You have to look closely at it to notice the cartridge attached since it resembles a cigarette lighter. On the far right on each stand you will see the Innokin box mods being the MVP in the rear and VTR in the front stand. The front row of each is for bottles of e-liquid while the holes in the front stand were not made quite large enough as specified to fit the 60ml size bottle since the vendor only used the diameter of the bottle's diameter not allowing the extra space needed and why those two are empty there.
