Just got it in the mail the other day. Its HORRIBLE. I was led to believe it was using a CHDNA 30 chip, its not. Its their own version and its very under powered. At 30 watts and a sub-ohm head @ .8 - feels like im vaping off a 3.7v device. The original vamo is actually better in my opinion. I'm ashamed I even pimped this piece of shit.
