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

Pros:
Cheap (since I bought it 50% discount), very bright (as you know, not 900 lm but bright enough).
Cons:
It has no mode memory.Mode change almost always fail (Stay Hi mode, need tens of time clicking to change Lo mode). Mine has driver of EAST-092 (direct-drive on high so not regurated to 2500mA, I opened the drop-in and confirmed inner circuit). Gets very hot on Hi mode, but is expected for P60 drop-in.
Other:
I connected the drop-in 100W CV/CC power supply. Actuall I can supply 6A to it. Of course the drop-in gets very hot in seconds. I replaced the drop-in to a XM-L T6 840lm drop-in (sku 164727). It is brighter than the drop-in of this flashlight.
Bottomline:
Though it is sold out, if it appears in 50% discount, it may be a good bet.
