You know you are a vaper when;
You understand Ohm's Law.
You drip and drive, (not safe) so you are on the constant hunt for the perfect drip tank...
You have that stressful unexpected event happen that would have required a cigarette and you are fine with grabbing a vape instead.
You have 190 yards of cotton yarn, 200 meters or resistance wire, fingernail clippers, tweezers, silica, toothpicks, dental picks, a dremel, paperclips, clamps, buttloads of ziplock baggies, wire cutters, screwdrivers, tiny allen wrenches, and a few boxes of misc. pieces and parts all within arms reach and still think "could use some more just to be sure..." (have to be prepared for the Zombie Apocalypse or the FDA)
You dedicated a major section of your cabinet/closet space for steeping and storage of e-juice.
You are just as concerned with the appearance of your gear as it's function.
You are willing to pre-order stuff even though you have no idea if it is any good.
You can tell the difference between nichrome and kanthal in an RBA/RDA by taste.
236 mL (8 oz) is a reasonable amount.
