Hey DudeMeetTyler,
I'd like to hear your opinion on those two lighters. I recently received the Zico and those are my conclusions but YMMV.
Handling:
Volt wins this one. The lighter is smaller, lies better in your hand and uses the normal ignition technique. The Arc is bigger and the ignition feels awkward at first. People who are excited and have sweaty hands aren't able to use it properly
Flame:
I often had problems with the Volt when igniting upside down. There are tricks to get it going perfectly but it takes time to find out. It also misfires if I don't drag on the GVG. The Arc on the other hand is superb. No misfiring and a steady flame making it my favourite when it comes to the flame quality.
Other things:
What I like about the Volt that it's easy to see how much gas is left in the tank as well as the protection against dirt in front of the ignition.
This might help somebody who can't decide which lighter he should pick but as I said YMMV.
For now I'm sticking to the Arc because some of my friends misfire during their inhalation which is really awkward.
