I'm kinda torn on this one. Shame about the anti-glare coating, but I can live with that. I do not care about holsters as I have so many spares taking up space it's not even funny anymore. Why buy a pocket sized light if not to carry in a pocket? But anyway... The mode spacing does look pretty crap, but the 84 lumen mode should be quite versatile and gives pretty good runtime, so the other modes might not be too important most of the time. 10 lumens instead of the 137 mode would be nice for a future iteration.
Now, all that aside, I like me that heatsink and side button design. Excellent balancing of ergonomics and engineering. Or so it looks anyway. It's hard to know if the larger heatsink is any more efficient than say, a P12, or how good the button is, or the UI, without handling one.
To those who have one, what is the UI on this? Is the side button just a mode switch like the P12 and E35, or can it be used for on/off as well?
