The camera would be okeysh.
The rugged design is basically perfect.
But for kids the 4/5 buttons, plus the complicated menu is not really usable.
If they click the wrong button they cannot get the next picture or video.
Maybe it is even me that, I could not get the "simple" operations.
I am not sure which age range they gave, but it makes little sense to market for kids that can actually use a go pro or the like.
So it would need a way more simplified menu and set of buttons.
