Mine just arrived about an hour ago

1st/Initial Impressions and thoughts....
Loaded the LG HG2's and a Freemax Starre Pro
(w/0.15 Ni Coil), locked in the Atty R and set to 35W & 460* F, then lit the Fires.
Nice

It is as advertised and reviewed
(IMO). I like it anyways. Of course, it's fresh out of the Box and not proven yet so far from receiving a complete "Shake-Down Cruise" as of this typing. But, so far so good and fingers crossed that it stays that way.
Finish is nice and provides good grip without being "sticky".
Buttons are responsive and give nice "click feedback" when pressed and just as I prefer them to be. Not too little or too much. Flush enough to not be obtrusive yet not recessed too much to become hard to access when wanted.
Menu and Functions simple to grasp, understand, and navigate
(as those with DNA40 experience know-this is my first one).
I really dig the new Battery Cap Design and the way they work.
Weight is comparable to my single 18650 SXMM APV.
Love the Ergonomics & Aesthetics of the Flask. Feels great in the hand and while putting it to use
(I'm a "righty").
Really like the Screen size and placement on the Mod. Makes it real easy to see what it's doing under fire and to confirm Settings.
The LG HG2's went in the Batt Compartments nicely. Not too loose or snug.
No Rattles or Noise at all even when "shaken"
(not stirred of course
).
Overall, so far, It's a Winner and Me Likey
Only personal dislike so far; wish the Stainless Atty Platform on the 510 Connection was a tad larger in diameter so that the Atty wouldn't contact the rubberized finish. This will lead to marring after several switches of the Atty. But I realize with the placement of the upper Plate recessed Allen Screws, it Is what it Is and all they could do without moving those mount Screws.
Also (since I'm already dreaming), be nice if the DNA40 had a Settings lock out at 3 clicks or something so the User could lock those and still be able to fire it. Oh well,,, ain't nothing perfect or anything that suits all 100%. I'll get over it. And as said above, the Buttons don't make it too easy to accidentally change them without meaning to. It's all good.
