Finally decided I need something more than what I'm getting from my trusty worn out istick 20 & aspire bvc tanks. I'll still use em, but now that sub ohming is more affordable and I'm upgrading after lots of price checking and shuffling in my head I came to the conclusion that the isub/coolfire IV is the route I'm gonna go. Just wondering if anybody's used this setup or has maybe another option they prefer for about the same price. I can get the 2 together for just under $50, and I actually like the built in battery and pass through that innokin has. My probably 3 yr old mvp2 still charges and still works, although the 510 connection takes a few tries anymore to get a tank to read on it. Was gonna go with the subox but with no spring loaded 510 and the extra cost I really don't know if I need that extra 10 watts, plus buying batteries, etc. Oh btw not that I'm buying one but fast tech is now selling coolfire IV style boxes along with a few other clones of innokin stuff. Guess they couldn't avoid the cloners after all as I believed.
