Flip side i think nitecore's innovation is 2nd to none, just think sometimes lights are rushed out too quick and QC can be a little hit/ miss. Seems to have improved though of late............just my opinion and sure they will vary and more so from fan boys
Having owned a good few of each brand, i prefer fenix..................If someone has owned several of each brand and prefer nitecore then i respect their view.....
Reflectors- well out of both brands, again i have found less specs of dust if any in fenix lights, nitecore i have noticed forms of contamination,be it dust,debris but very small. Not enough to effect the light/beam .
Whats put me off nitecore of late is the cell layout , dont like the way they have gone and make daft errors like wrong diagram/instructions on the side of the tm06 body. Things like that did end up bugging me, i kind of thought after a few month,if they make errors like that,what else can they do. Admittedly either brand could be effected with "school boy errors".........again just imo.
