I've struggled to find an easy (ie EE-free) way to backup multiple iOS devices (iPhone, three generations of beloved iPads). Most flash drives worked fine, but the weak point was the application support - usually clunky and complex. So far this drive and its app have worked flawlessly (I use it in conjunction with the RAV Power Hub to wirelessly connect different devices without a tangle of incompatible dongles. Damn it, Tim Cook). My biggest complaint, and it almost stops the show, is that it doesn't work well with RAW photos, but none of the others I've tried work. Minus one star.
