Got mine today. Overall impressions after a few minutes are good.
Pros:
The light feels solid, but not too heavy.
Knurling feels pretty good. I like aggressive knurling, but this feels like "medium".
All parts fit together well, without any looseness or rattling.
The hotspot seems pretty bright for stock. Subjectively not as small or as bright as a Convoy L4 with a XP-G2 swap, but the sun is out and I have no instruments to measure lux anyway.
17mm forward clicky switch fits without any issues and works well. Simply add a metal washer toward the rear and discard the rubber o-ring toward the front.
The AR lens is flawless to my eyes.
Cons:
There are some chips in the anodizing throughout the body, presumably from being manhandled in transit. Perhaps placing it in a crappy cardboard box (like most Chinese lights ship in) would have greatly reduced these chips.
Stock lens was dirty and had lots of smudges.
All threads were bone dry, so I spent a few minutes lubing everything up. I would've done so anyway, so not really a major issue.
There are some imperfections in my reflector. Looks like some dirt/sand was trapped underneath the layer of chrome(?).
The beam is slightly ringy in the spill zone, but it's pretty mild and tolerable.
Edit: The unit I received has a green o-ring in front of the lens, as well as a green rear switch boot. This was unexpected; I would have preferred plain black, but it's a minor detail.
