Pros: -GITD tail cap.
-Attractive olive grey finish that goes well with the army ACU color scheme. Seems to resist scratching well. Could very well be full HA.
-Oring seals on glass and between the body halves.
-Fits protected 16340 cells perfectly.
-knurling provides perfect feel.
-Slots in tail allow 550 cord lanyards or other custom options.
-Very nice medium setting with a good amperage for max efficient output.
-Useful low and very bright high with respectable throw for its size.
-Bezel is not sharp and fine in a pocket.
-Well made. Very good solder joints and construction/threads.
-Pill transfers heat well to body.

Cons: -Oring at glass is not GITD but unseen Oring between body halves is GITD. WTH?
-Could be smaller diameter. Its built beefy and I think this size flashlight is best served in a minimalist size.
-Will not tail stand without a simple modification.
-Not so good on primary's. Its certainly usable though.
-Not an R2

Other Thoughts:

Bottomline: I bought two of these and both are really well made. I bought them for there output on 16340's and with the thoughts that I'd make a lanyard out of 550(para)cord. I figured I'd have to fix alot of flaws before I'd bring them into the mines, but these two were really perfect mechanically and electrically. I wish they were smaller like my much more expensive single cr123 light, but for there advantages the size hasn't bothered me much. wonderful flashlights!

Pros: There is an o-ring in the head, and its GITD green
The threads are strong and durable
The brightness on high is about the same as my other cree Q5 lights (which means its extremely bright)
The clicky works good and is GTID
It is very easy to grip due to the pattern engraved in the body
It doesnt have any issues with bad connections, off center mounting, loose parts, etc (many of my DX lights are plagued by these problems)
It can tail stand
BEST PART: You can easily fit a key ring in either of the extended loops by the switch. These loops are VERY strong, and there is two of them encase one eventually breaks. I've gone through about 6 EDC lights, and eventually the part that holds the key ring in always breaks (I'm kind of rough with my key chain, and it gets a lot of use)

Cons: I don't know if it really is HAIII (I don't know how to really tell). It seems to be much harder to scratch than some of my other cheap DX lights, but I can't confirm that it is HAII.
SOS mode is useless... I don't know why they include it
Strobe is useless but it is fun to play with.

Bottomline: The Best EDC light that I've found on DX (and I've tried alot of them)
