Just discovered something that may help some folks with fire button issues on the iTase SVD.. I (stupidly) went back to cigarettes for a month, went back to vaping and found that the fire button was red when I pressed it, acting like it had a dead battery.. Well, it's known now that eliquid leaks through the seals, so I tried putting my mouth over the fire button with it disassembled and force air through it. I guess juice gets in there, blowing air through seems to clear it, works fine now. Just sayin'..
