Hi gurus I have just purchased a ROG 3 strix edition and while googling an OtterBox for it I came across something called an Arion case,I believe. Can someone please educate this moron in what it actually is. It looks like an alternative tradies case but from the adds it looks like it replaces the back cover. Is this correct or should I watch what my wife is slipping me . I am not a gamer I just love Asus phones and could not resist this beast . I am not a tradie I am a distribution driver so I need something that can protect my investment from the Day to day, All day 5 days a week, from the knocks and cra$ I put my phones through. Will this do the job????
