Cool deal! What coil ohm and wattage to you normally vape? ThanksI've had the Smaug mod for a couple weeks now. No problems at all. The screw adjustable 510 is reversed threaded. Takes about 9 hours to fully charge through usb from 3.5 to 4.2. The mod will stop firing if battery gets down to 3.2, for protection. The chip is pretty good. Very good battery life, quick screen shut off's and little low brightness help that. The ohm reading is a little off but not too bad are unusual for most chips out there. I think it is a good value mod for the money.
