Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
+Extremly BRIGHT on High +Low is really low, nice runtime of ~50 hours +3 usefull modes (H-M-L) +Thick aluminium body, resistent +Can be fully dissasembled easily +Glass lens, not plastic as DX description +O-rings everywere, don't waranty waterproof but will handle a splash
Cons:
-Typical P60 problem - Bad heat transfer from the dropin to the body. -2 useless models (SOS and Strobe) -Not properly packed. Mine came with a dent on the bezel -part retaining the lens is a cheap plastic ring. -A bit heavy for EDC, due the thick body.
Other:
This is a extremly nice flashlight. my favourite P60 host at the moment. It came wraped in bubble plastic, but due a poor packing the flashlight was damaged during shipping. It has a dent on the bezel and the plastic ring retainint the glass lens can't be dissasembled. It is missaligned and I'm afraid if I force it out is gona break.It's a cheap plastic threated ring.
Bottomline:
After using it on High for 5 minutes, the head of the flashlight gets only warm. If you dissasemble the head and touch the dropin it is really really hot. So hot I can't hold it for 2 seconds. This is the typical P60 dropin problem, the amount of heat generated by the led (XM-L are cooler than P7 and SST's, but still really hot) doesn't transfer to the body properly, and can damage the led permanetly. I'm gonna try to use some aluminium foil to improve the heat transfer from the dropin to the body and head, and also apply a bit of thermal silicone on the reflector threads, as they are a bit loose.
