I will speak from a" if it was ME" point of view as i have had no experience regarding Fenix in warranty issues.IMHO it is absolutely unacceptable in every way,i also think it depends on the seller/retailer in your state.If good they will check it over,give you a replacement(helps keep customers too) and send light off themselves.
Anything less is not acceptable,i believe nitecore is bad,but this has to be on a par or worse..............
Only time i have had to deal with a company is led lenser(yes that company,the one thats "crap").I spoke to ledco(uk distributor) free switch and carrier posted for next day delivery,all free,no questions on age,where bought etc and it was my fault which i told them.
If i had an experience as you are,i can tell you i would never ever buy another light from them or whoever the manufacturer would be,waiting a week or so is acceptable,month is a no no,longer well...........
Its not like a $5 light(not that it should matter) so i would be getting my money back,and fighting it too over principle but thats me and my opinion.
Maybe ask on the dealer section,as each case varies,not saying your wrong,but you need the full picture,i dont know age of light,where it was bought etc .
My comments are if purchased new from a shop,buying over seas changes things........depending on brand of course.
I have heard many praise from Fenix in past,capolini is one of them who had issues and had excellent customer service.
So maybe a message on the dealers corner part of the site,maybe that might get things moving,good luck and sorry to hear of problems,it would drive me mad too...
