I got it yesterday, got around to trying it out today. Nice looking, solid as hell, weighs about the same with battery and juice as my REO with a Derringer. My biggest complaint is the center post which does nothing except get in the way and short the coils out if they're not positioned correctly. I put some of the wick in between the coil and the post to guard against accidents. I put two 28ga x 7 wrap 2mm coils on it and it works beautifully. I wouldn't try anything below 1 ohm, it would probably melt the insulator.
As I suspected, the mod and RDA will only work with each other, and you can't check the coils on a regulated mod or ohm meter. It's comfortable in the hand, the flip top isn't awkward at all, and the jack-in-the-box drip tip works great, which is good because a 510 tip won't fit.
Not quite a gem, but definitely not a turd.
