It's not fake. Just some misunderstandings. I wrote about it
HERE
Also
@Sungmoon Jang mentioned
HERE as well.
And again my post
HERE
As mentioned in
Panorama S thread, the eBay seller shpkorea has at the moment only Korean version and with CPL filter will be available soon.
@jokiin mentioned
HERE that Panorama S with metal ring available, and this is the only place you can by it from RoadCam ONLY.
Soon shpkorea also will stock CPL filter + international version of Panorama S.
I believe that there is 90% maybe misunderstanding from your side ( maybe not reading all info ) and 10% shpkorea to post only one picture with metal ring, however all other big size pictures does not show metal ring.
Also there is nothing mentioned about usage of CPL filter or metal ring from description.
Anyway, thats no point to find who to blame at this stage. Most important to work out situation via communication. Shpkorea has been great seller and giving a good aftersales support and I believe you will find solution.
Of course if you are good in DIY, it's not that big job to glue metal ring to the front of lens surrounding housing. I would use thin metal from those minty-candies, kinda tic-tac, but in metal boxes, if you know what I am saying. It very easy to cut them even with domestic scissors.
