I am getting really tired of messing with my 510 all the time. One day it is great! The next it wont draw. The next no vapor. The next no taste but air. The next the atty floods constantly. The next the batteries don't seem to last even one cigarette worth of drags. On and on and on!!! I just want it to work! I do the same thing each time. I drip two drops on the atty. Im not an idiot that cant figure out how to smoke these. When it works by dripping it is fabulous. Its all the other times that I want to throw it as far as I can.
