Biggest issue I had with an FWAA was a driver wire desoldering itself from the star of my FWAA Ti.
… but it wasn’t the light’s fault.
I had used the shortcut to turbo from off of “click + click-hold”.
That mode gives instant access to turbo and overrides the thermal protection as long as you hold the button down. After all, if you’re holding the button down, you shouldn’t need thermal protection…. you’ll release the button when your hand starts to burn long before the light is damaged.
Well that’s probably true for the aluminum and copper versions. Not so much for the all-titanium version where the head can be burning hot while the back of the light remains cool to the touch.
Fortunately, it was fairly easy to resolder the bondwire back on.
