Got mine today. My sixty second initial impression is that I like it. It won't win any awards for being the smallest AA powered Cree light, but you've already figured that out by looking at the pictures on the DX site. I'm not sure why it has such a large reflector if it wasn't designed to throw better than your average AA light. Regardless, the reflector works extremely well. I may have been lucky, but mine has the best centering I've ever seen on a Cree. The texture works very well too. There's nearly zero "Cree ring". I really like the beam on this one.
Build quality is very good. All the parts feel sturdy and well machined. The threads work as they should, and everything lines up well. There's a good heft to this little light - it feels very solid. It's too bad it isn't hard anodized, but it wasn't expected at this price.
The tailcap has the typical reverse clicky, and it seems this one won't tail stand. It came with a lanyard already attached. The window does indeed appear to be glass.
Maybe later I'll pull out the lux meter and try to confirm the readings reported on DX. I might try to get a beam shot, too.
