On board usb charger works. Red when charging and turns green when charged and light stays green until you unplug it.
Screen is very bright. The 510 deck is adjustable with a small allan wrench. Also has atty ohms lock
Comes shipped in a non fancy black box... no instructions...just the mod no extras
So it's exactly the same as the authentic (including no instructions/extras).
I'm a bit disappointed to hear that their reference to a spring loaded pin (on 3F site) was incorrect. The wrench thing is fine (rarely necessary), but spring loaded might have been nice.
