I have mine for a week now, and have mixed impressions.
Nice light, looking good, and the beam is excellent. Very collimated spill for this little reflector, I say well done. It is bright, too.
But it is too stiff and "sticky" to turn IMHO, even when excessively lubed. My biggest complaint though is the level spacing ... way too narrow. It is hard to distinguish the three levels at all, they are next to useless IMHO. Runtime on alks is not that cool either it seems, but I haven't done any controlled testing, just playes with it.
Never tried E92s either.
