I have never had issues with overheating on any of my Z240s but I have problems with the silly push lock on the 1 or 2 preflash button. On a couple of my Inons this just doesn't hold and there is nothing more annoying than shooting away and discovering the button has popped and is out of sync and not firing when you want it to. That and the modelling light button just seem like bad design (I am always accidentally putting the modelling light on temporarily when I don't want to).
It is a real shame that they haven't taken this chance, as it will stop me buying the new version.
