A neat little light there.
The thing is, though, while I understand these NiteCore lights are of excellent design and quality, the UI and features just seem too complicated to me. I like fiddling with my computers and cameras, but I want my flashlights to be simple. I mean, it's a FLASHLIGHT, not the Space Shuttle. And it's not a Light Saber. A couple levels of output, maybe three, and that's it.
And as the poster above pointed out...very 'aggressive' styling. Sure, a strike bezel can have its place. Sure, you want the light to be strong and tough. But I think there's an over-emphasis on things 'tactical' these days. Simple solid construction, some good knurling or checkering (some one should try machine stippling) maybe a step up or down in tube diameter, to keep the light from being too smooth and slippery, but nothing more, please.
I can appreciate the need for a good, small light, in a self defense/home defense situation, primarily for target ID, and to a much lesser extent to momentarily disorient your assailant. But I'm a civilian. The last thing I want to do is have some gadgets that make the cops or the DA investigating me after I've had to use force think I'm a Rambo wannabee. If I have to use force to defend myself, I want to appear as low-key and innoffensive as possible, in terms of dress, weapon choice, and even, yes, my flashlight. Now, if you're an LEO, by all means, load up for bear, and get the meanest baddest gear you can. But for the rest of us, I think 'low profile' is a much better way to go.
Just my $.02 worth.
