I'm telling you, never do this.
Never take off your drip tip to check the saturation levels of your cartomiser in the
tank, and then test fire it, only to have a red hot
ejuice glob spit directly onto your eyeball. OMFG the pain. I looked like an extra from 28 days later. Ouch. Ouch. Fuuuuu
I'm ok though. Biut just don't do it. ok?
