Bought a VV. Love it. Got a T3 with a few replacement heads. They are driving me nuts! I use them and for the first few days, about a week... They ROCK! Then all of a sudden they start gurgling, flooding the batt, and having a very very light hit. I tried changing the voltage, kinda helps for a few drags, then back to the same old song and dance, flooding gurgling ect... Am I doing something wrong? Seems people love them... I'm about to give up on them.... PLEASE HELP!!!
