I don't know what's been going on with my VK lately. I'll take a puff, it'll work fine and then it'll stop working. I had that happen a few months ago with one of the batteries but figured it was because I dropped it. It hasn't worked since, no matter how many times I've charged it. But I never dropped this one and now it's doing the same thing and has been for about three weeks.. I've charged it overnight and still get the same results. I've also changed cartridges and brands but no go. I asked for sighted assistance and was told the light worked properly as it charged. Can anyone tell me what's going on? Could it be because I left a cartridge on it for awhile and didn't smoke it? I really enjoy this ecig and it would be ashame if I had to throw it away. On the other hand, the deals for a new starter kit are sweet so I might consider that when I can afford another. Thanks.
