This thing hits really really well, and those Visions are probably the best visions I have had yet (Maybe because of how well they work on those voltages. It is REALLY unfortunate about the other issues. I've heard of ONE other person having the similar issue, but then I've seen one that had none of them. However this isn't a "I can fix it" problem, it's an actual issue with the mod that I can't fix. I CAN'T fix the fact that it won't fire with any boge 2ohm, smoktekk 2ohm, vision 2.2ohm tank. Also, the issue with the Pos battery connection isn't one that can be pulled out a little....however CAN be fixed with either foil or a dab of solder. This was really disapointing over all, I wouldn't care if it was a peice of crap that I hated all around. What makes it really disapointing is that I LOVE the way that it fires and works, especially with those visions.....
