Just received mine as well. Feels nice and sturdy; threading on the battery cap is buttery smooth. A little bit of rattle to the buttons, but the slight clickiness and tactile feel is nice. On the curve of the battery enclosure, the seam is raised slightly near the top 510 connection, enough to feel it if you run your finger over it, and on the upper edge of the screen their is a slight raised "ding" as if from a screwdriver. The anodizing or painting is a bit off in places, uneven or light. The surface is both smooth but their is a grippiness to it, so it's not slippery.
I don't have time to chuck in a battery, since I am leaving for work as soon as I hit the post button. All atomizers have fit flush on top, with only a slight gap on the Magma clone due to long threads. Attys might sit differently once I put a battery in it.
I'll have time to play and test it after I return from work, in the wee hours of the morning.
