Flash seems fine.
I do have that rattling sort of sound coming from the flash housing but I never thought of it as an issue. I think it is just those two shiny arms that limit the upward travel of the flash. They have some free play when they are not under tension. You can see that if you hold the flash half open and touch the arms with a matchstick or something. I don't consider it an issue although it would have been nice if they put a rubber bush or something to prevent them from rattling.
