i just received a tank atty and some tank cartriges in the mail, am going to make my ego 650 a tank. put it together with juice and all and am getting very little vapor and that metal taste, i cant taste my juce at all. i took it apart and blew out the atty and put it back together took several puffs and its the same thing. i took puffs without pushing the button nothing has changed. isnt the cartrige suposed to get a hole in it and how can i tell if it does have a hole in it? stupid newby question i know what am i doing wrong?
