I have just this minute found that putting the juice in the back side yeilds WAY more smoke. I was about to toss my VaporKing at the wall and buy a pack of cigarettes - I just couldn't get decent vapor off of the cartridges that I have been refilling.
Of course, that could be because I have refilled them too many times - time to buy new cartridges
