Out of my fenix lights , all the ano seems pretty good,i have been happy with the quality side,ano etc. The only single negative i have had is one e25 being almost DOA,flickering then nothing,this was replaced FOC by Fenix so all good and of course not ano related.
My lights 2 xe25,one is almost used daily in work,this is still mark free so far.
e05ss but stainless so n/a...........stainless is great for key edc lights though,really does look like new after months.
tk75vn/tk61vn/tk51/tk50
Admittedly none have been thrown around or dropped onto hard surfaces(other brands have not either but chips have appeared)
So from my experience reg Fenix,its good,but as said so has olight too. I will state that the cheaper olight i3s is shocking when it comes to the ano,as with the nitecore T0. Now part will be down to living with keys,but i am sure the ano is not up to the same standard as more expensive models(no set standard maybe...dont know) Nitecore has not been quite as good for me,i am being picky here,the tm15 and p25 have very slight signs of ano chips(might have even come like that tbh as that small...........dont know as its not something i noticed straight away nor do i inspect every light with a magnifying glass :laughing: (maybe i should)
Cheaper branded lights like convoy have proved very good also for me,again no real heavy use and not sure what claimed spec the m2/s8 actually is.
I do believe that manufacturers in general apart from the minority (maybe surefire etc)do have different tolerances(or off days). I have read for example different reports of zebralight,from excellent to poor anodizing............i dont own so cant comment on my experience regarding that brand..........yet
Back to the OP,this pd22ue that is new,has it been abused any,left with metal objects,keys/coins etc,dropped at all......,i am presuming no,if so i would contact Fenix with you issue/concerns and hopefully it should be addressed. I would not be happy if marks/wear appeared without good reason,or i could tell the finish was poor. Maybe drop them an email and take from there,after all ,your not happy and for me it should be sorted by Fenix ,as looking after customers is key to having a good reputation which they do have imo......................just a thought
