I've had my cloupor dna30 for two weeks now. It's been flawless no finish problems/flaws.
I do agree that the Ohm reading it provides is approx .1 off.
The battery indicator shows the battery dead at approx 3.5 volts, but it will still vape normally for approx 2 hours before it stops firing.
I have used it with protank1/2, puritank, and kayfun 3.1 with no issues. I had thought that the 7W minimum might be a problem for my BCC tanks, so far so good.
I have never had to hit the fire button more than once when the DNA is sleeping, TMK.
I've not used the on-board charging feature, just drop in a new bullet and go.
I haven't sprung for a FT clone, still licking my wounds from buying the cloupor from a B&M (love at first sight is expensive).
