Just got a replacement after the pin corrosion, how is your f5 holding up?

Hi guys,

I just got a brand new replacement for my Fenix 5, but I believe it's an old production unit, since it has a 7 months old firmware (12.40) and the silver pins like the other one.

I'm expecting the same issue I had before in the next weeks or months, so how is yours holding up? I read about people asking for 2 or more replacement after just some weeks.

Also, any news on how to prevent this to happens?

edit: old serial was 5361xxxxx, new one is 5363xxxxx
