I've had a Vamo 5 setup with a Protank 3 since February, and it was working great for me. Then I shattered the outside screen on the sidewalk, so last Sunday, I got a new Vamo 5. Two days ago, It started saying I had a low battery, when mine was fully charged. I kept switching out the batteries, and nothing worked until I switched out my wick (which was new). Yesterday, I had to pick up a new tank, and ever since, I'm having a combination of that Low battery screen with every other wick, and my wicks keep burning WAY too quickly, even on low wattage. I've gone through 4 wicks since yesterday, and I can't even get a decent drag without burning. I'm so frustrated!! Does this sound familiar to anyone?
